Can non-guests buy a day pass to use a hotel pool in Turkey?

When picking a hotel for October, a traveler asked if pools are heated enough for comfortable swimming — last year at Papillon the adult pool was chilly, while the neighboring Bellis had a well-heated kids' pool; she was looking for a new option with guaranteed warm water.

In response to the day-pass question, locals clarified there's no separate paid access to open pools — each hotel's pool is free, but only for guests staying there.

The one option with paid access open to everyone is the water park in Bilek (Belek area), which requires a regular ticket rather than a hotel day pass.

The original request was specifically about finding an open pool or a hotel offering an affordable day pass for use without staying overnight.
