Amex platinum UK has quite good offers . Not sure if they do the same in the UAE.
Just used a £50 off £250 spend for hilton and had a similar one for Marriott as well.
Also the hotel status (hilton,marriott etc) is quite good.
If you like a bit of luxury then booking hotels through amex fine hotels and resorts gets you special perks like breakfast room upgrade, special amenity at the hotel etc
Just used it for a holiday in spain
The main issue is the foreign transaction fee which is nearly 3% for UK cardholders.
This was offset by a £60 off £300 spend offer that i has saved to my card. ( offer was for leading hotels of the world but seems to be connected to fine hotels and resorts and they paid out)
Not sure if amex platinum charges the forex fee everywhere?
