NOT the airside hotel for sure, it's fine for convenience, BUT you pay hansomely for that convenience !
There are lots of good hotels close to the airport, and even slightly further afield, at this time of year there are some great deals to be had, "summer sale" time due to the intense heat.
I've stayed at the Intercontinental and Crowne Plaza in festival city, not a 10 minute taxi ride from the airport, as well as the one's that EK put you up in if you have a long transfer.
Do a search, there are some great bargains to be had, and it gets you out of the airport !
