I see that spa area must be paid for unless included in your rate but does this also include the pool area or can this be accessed all day?
The access to spa area must be paid, in our case it was included in the rate (we specially mentioned it to the hotel). This includes the pool area as well. Furthermore you have to book to get access to the pool area because it is a small area and you don´t want to be bothered by many guests at same time, so it is the hotel policy.
