Hi onfo, given that you have not visited Dubai before, I urge you to get out and at least see something of the city, if only for three or four hours. There are any number of excellent restaurants where you could both enjoy a good dinner AND take in some great views. A number of members here are very familiar with the foodie scene and will hopefully come on with specific suggestions.
I always consider it something of a privilege to be able to travel in this big world, and let's not forget how many people who - for one reason or another- never get the opportunity.
I have yet to see an epitaph on any tombstone reading "I wish I had spent more time in airline lounges"
