Operator comparison

How do I stop towel-reserving chaos without adding staff burden?

Replace the morning towel race with a time-slot reservation guests make in the phone browser, and a live operations view staff already have on shift.

That's the short answer. The longer one is below — what "solving" the towel-wars problem actually requires, and which route through this category fits your property.

Best fit for

Hotels and resorts that want QR access, time-slot rules, and a staff-facing operations view.

Usually not needed for

Properties that only want consumer day-pass demand generation rather than hotel-side operational control.

The problem — and what "solving" it actually means

Hotel guests reserving sun loungers by throwing towels on them at 6 a.m. — colloquially the "sunbed wars" — is one of the most common complaints in resort review data. It rewards early risers, leaves loungers visibly occupied but physically empty, and generates recurring front-desk disputes.

Not every product called a "sunbed reservation system" actually changes that pattern. Many offer only crude full-day or half-day blocks — a guest reserves a lounger for the morning or the whole day, occupies it briefly, and the bed sits empty for the rest of the time anyway. The dispute just moves from the deck to the booking screen, and the early-morning race can turn into a midnight race for tomorrow's slots.

Solving the problem in a way guests notice usually takes three things working together:

Granular time slots

Not full-day blocks. A lounger that’s free for two hours can actually be re-booked instead of held all day.

Live availability

Guests see what’s open before they walk to the deck — not “reserved” labels they only find out about on arrival.

Multi-zone configuration

“Main pool taken, quiet zone still open” is visible up front, and zones with different demand patterns can have different rules.

Add a hotel-side operations view (overrides for VIPs, weather closures, group bookings) and you have something that fixes the guest behaviour, not just the booking interface. Hotel-side systems differ widely on all four — which is what the comparison below is about.

What differs between the kinds of product

The columns are kinds of product, not individual companies. Naming vendors dates a page within a week and tells you less than knowing which sort of thing you are looking at. Within a column products differ, so where that is true we show Varies and you should check it in a demo rather than take our word for it. Last reviewed 13 October 2026.

Reading the table. ✓ part of the standard product · ~ differs between products in that column — check it in a demo · ✗ not what that kind of product is for. The three shaded rows are the ones we have not found anywhere else; everything else in our column exists in some form elsewhere, and we would rather you knew that before the demo than after it.

Where we are not the answer. We do not post charges to the room folio and we do not connect to your PMS. If either is a requirement, Vendor C — or Vendor B with a PMS connection — is the right purchase and we will say so on the call.

Five questions worth asking every vendor, including us

The answers separate these products faster than any feature list, and you can get all five in a ten-minute call.

  1. What happens to a reservation nobody turns up for — and how does the system know they did not turn up? Most vendors describe an automatic release. Ask what triggers it. If it depends on a guest being checked in, ask who does the checking in, what happens on a busy Saturday when nobody scans, and whether a guest who is lying on the lounger but was never scanned loses their booking.
  2. How finely can the day be cut, and can we change it mid-season? A fixed morning/afternoon pair and a configurable set of bands behave very differently once August arrives.
  3. What does a guest have to give you before they can book — and whose record is it afterwards? An email address typed into a vendor’s form is a vendor’s record. Ask where it is stored, under whose contract, and what your data-processing agreement with them says.
  4. Does any of this need a connection to our PMS to go live, who runs that project, and what does it cost? Integration is genuinely useful if you need charges on the room bill. It is also usually the largest item in the timeline.
  5. Can you show it running on our own pool layout, live, before we sign? Not a slide and not a recorded walkthrough — your deck, your zones, your rules. A vendor who can do that answers most of the other questions along the way.

Which route fits your hotel?

Three different products call themselves "sunbed reservation systems," but they answer three different buyer questions. Match the route to the question you're actually asking.

Choose hotel-side ops if you need to manage your guests' poolside

You're running the deck. You want guests to reserve from their phone with no app, you want staff to override in real time, and you don't want a months-long IT project.

TowelsOn fits this route.

  • QR access at check-in, browser-based, no app install
  • Per-room code fallback for guests without a smartphone
  • Time-slot reservations across multiple pool zones
  • Hotel-staff operations dashboard with live overrides
  • No PMS integration required
  • Free 3-month guided pilot — setup done for you
  • Live in about 1–2 days from sign-up
  • Multilingual guest UI · published pricing

Choose a marketplace if you want outside demand

You want to sell day-passes for your pool or beach club to non-guests — the hotel isn't the customer; consumers are. That's a different problem from managing your own resident guests' poolside.

This is Vendor A in the table above — a guest-facing app that sells day passes. Worth checking before you choose one: whether the guest ends up with an account at your hotel or at the marketplace, and what the booking costs you per guest.

  • Consumer mobile app + account-based booking
  • Day-pass model rather than slot-based hotel ops
  • Built for demand-gen, not for managing your own guests

Choose a broader suite if you want one vendor across systems

You want a single contract that covers PMS, POS, spa, restaurant, and sunbed booking together. Sunbed handling will be one module among many.

A broader hospitality software suite fits this route. Trade-off: less specialised on the sunbed flow, more setup overhead.

  • One vendor across multiple hotel systems
  • Sunbed booking is a module, not the focus
  • Often expects PMS integration
