I've sent them a message via their website Lynsey but did see a reply to another question regarding swimming & this was their reply:-

We would like to let you know due to the weather conditions the summer season begins on 1st of May. Also on March we have an outdoor heated swimming pool . We wish you a nice weekend. Best regards Liberty Hotels Lara Team

Will let you know when I receive a reply.

I have stayed Ian the delphin palace which was niece , not as nice as the hotels in beleck just up the road. The Rixos Premium was lovely and so was the Xanadu . Do you realise that the average temp in April is only 16 degrees. Xx

Lynsey they've replied with a very similar response:-

Hello dear Glynis, Thanks for your question. We would like to let you know due to the weather conditions the summer season begins on 1st of May. Also on March we have an outdoor heated swimming pool . We wish you a nice day. Best regards Liberty Hotels Lara Team

You alsmost can't go wrong with any hotel in Lara.

Looking for decent hotels in either area with water slides for June.
does anybody have any recommendations please?
Never been to that part of Turkey before so any info on the areas would be much appreciated. Must admit I’m getting very mixed messages from people I’ve spoken to.
