The swimming pool service is a complete disaster. The stuff is selling the multiple entry pass which should work with no limits, but after several visits the stuff starts minute count which comes as a huge surprise. Once you leave the facility you are asked to issue an extra payment per minut charge (like you carry cash or cards in the swimming pool form you hotel room.) Room charge is not supported. So for a 5 Star hotel it's quite a fall back in the 80s.
If you mention the swimming pool stuff that you will come back later to cover the extra charge they will treat you with security. Absolutely NO GO for a 5 star hotel.
