I have used the lounge in Bangkok and whilst its nice its nothing special. if you dont have the opportunity to use premium lounges much, then its worth turning up early for the experience, otherwise i wouldnt bother.

I dont believe Emirates give out amenity kits or pyjamas on short day flights, they didnt when i flew first with them, but do what i did and ask and if you have a nice attendant/purser they may source one for you. They got me a whole bag of goodies, but i may have struck lucky.

The shower on the plane is worth doing just for the hell of it !
