can anyone tell us what to pack, and need to wear at xmas.

i am getting too many different reports.

first off i am told, why did you book sharm at xmas, it isnt at all hot??????? you wont be able to sunbathe or get the shorts and the swimwear out, as it wont be hot and the pool and the sea will be freezing.

then i am told it get dark suddenly at 4pm,
then i am told it is cold and freezing at night, and we will need a coat?????? now do i take a paddington bear style coat, or just a fleece or just a slopy joe???????

then do we have to SMART and all dressed up for the xmas gala meal which is on xmas eve, and if so i havent a clue if we need thermals or just some summer smart casual or to dress for black tie dinner???

HELP

can some one or every one please let me know, i am not desperate, and thinking of cancelling and going somewhere that will actually be hot at xmas, (not the canary islands).
