you can stay 5-6 hours no problem but they will charge you full day rate. you would need to book 6 rooms for 11 people as rooms are for for two people they won't let 11 people in one room even if you take turns and only have two at a time in that room . all guests need to register.

Hallo Treho, das Frühstück wird von 7:00 bis 10:00 Uhr morgens angeboten! Schöne Grüße vom Top Resort auf der Nettwetterinsel Koh Chang! Michael

Ab wieviel Uhr gibt es Frühstück?

Go to the area on the arrivals floor where all the hotel reps are [maybe gate 4 or 5] someone will be able to get hold of SG rep.

Yes but it is the type that covers the whole of the bathroom. Keep damageable items and towels outside and expect to dry toilet seat afterwards.
