We stayed at the Rex Turtle Beach in April this year, The evening dress code is long trousers for men and is smart casual. Although there were a few people there with 3/4 trousers and T-shirts and I'm sure nothing was said as they wore the same another night. Mostly the men wore long trousers and shirts or polo shirts. Women just covered up a bit - obviously no bikinis in the restaurant in the evening, but anything goes - just don't bother taking the Ball Gown - you won't need it.
The rooms with the best view are on the 2nd Floor at the far end away from the reception. We had a first floor room and that was good, but the 2nd floor was better (our friends were on the 2nd floor). The only problem is - it is a long trek to go for dinner or breakfast in the morning. It's ok at first as you feel quite secluded, but by the end of the week it really was becoming a trek. If you have forgotten something from the reception and you have just got into your room, being tired out from doing nothing all day, then it becomes a bit of a pain. But in saying that, I would book the far end rooms next time. If you want to be able to walk straight out onto the beach - the ground floor rooms are OK, but you do not see the waves hitting the beach as the beach has a steep slope to it just before the water's edge. The rooms by the pool are mainly taken by people with young children.
Sunday School - we got there about 10pm and it was just getting started, we arranged to be picked up at 12:30am, but I understand it goes on until the wee hours. The only Sunday that we were there was our first full day there and our body clocks hadn't altered - so we were shattered but I didn't want to miss it. (We were only there for a week).
We hired a jeep for 3 days and it was great to get out and about on our own steam. But two 'tours' that we went on were totally un-missable - Frankies Rum Punch Beach Party (definately the highlight of our holiday) and CocoMotion - a speed boat ride with stops at different bays to snorkle and swim, or just see the island from a different angle.
Hope you enjoy it as much as we did - We will be back !!
