Thanks all for your replies.
The two bedroom suite was the ideal as our three year old has been in her own room for a long time now and when we have had to stay in a standard room, we all end up waking each other up.
Seems from what youre saying is that the Marriott harbour suites in Dubai may be the only one that has two bedrooms as standard.
May need to to think more about MVC and paying the upgrade costs - I’m assuming I can do this at time of booking?
thanks again.
