I would do two rooms at a moderate resort. Personally, I would want to stay at POR, but that is mainly cause of the location and I love that they surround their grounds in pools. The resort rooms sleep 5 so your 7 people will have a bit more space and feel quite comfortable and still have themed slides, as opposed to being in value resorts and not having slides. I need a slide and I like to be able to take a boat somewhere. The value resorts are just way out there. If I were staying at one of these places, I would probably be very frustrated with getting around the world, esp. with a baby.
