We stayed 2 nights at the Hilton Fort Lauderdale and it couldn't have been any better. The rooms are all suites with a kitchen and living room. It does cost more than just a hotel room, but we ended up saving a lot by eating in instead of going to restaurants - especially with 2 kids to feed!
The infinity pool is very nice with a view of the ocean, but we found it crowded even during a weekday. The beach is right there and you just need to cross the street. You can also rent bikes from the hotel and it's nice to take a ride in the evening for ice cream!
It's a bit too expensive for us to stay here regularly, but we really loved The Hilton.
