Great! That's what we are planning- Abu Dhabi Sun-Thurs and Dubai Thurs-Sun. Can't wait to get to know both cities.
The price differential is high, but not as big as I would have thought- ~$150-$200 difference a night between the Emirates Palace and the Crowne Plaza for the nights we are considering, and much less differential for the others...
I've heard there are a lot of good ones, but do you have a true "don't miss" restaurant for Abu Dhabi?
