Send an email to the hotel and they will tell you that they will try to accommodate you. I prefer the mirlos due to the larger reception area but both hotels have the same sized dining rooms with flintstones themed Betty's kitchen. The hotels have both been refurbished over the winter
We went the 24 June for a week and didn't have any bother getting a sun bed, the management aren't strict at all as we seen people reserving beds from 5.30. Definitely not something I would be doing, we didn't even go to the pool area until the afternoon.
