going in april for 5 days. plan on having several guests visiting (several nights each, not overlapping). have 2 br villa. will each group of guests have to be registered when they arrive? i assume arrival and departure dates for each group cannot overlap unless total occupants remains under 8, the max # in the 2br villa. on the same theme are unregistered guests allowed to visit for the day (not staying overnight) if accompanied by a registered guest; assuming its only a small number of friends? would they be allowed to use the facilities, ie pool, spa, golf; again if accompanied by a registered guest?
