My kids had the opposite reaction, after about Day 4, they were over the clubs and shows, and dinner, etc. They still had fun, but would probably have had just as much fun getting off the boat and going to the parks. For us adults, I enjoyed the relaxing and not having to pack and unpack every time you turned around, but to be honest, because we just aren't into things like Palo, spa, etc., a 4 day would have probably been just fine for us. Also working against us was having a 4 year old that limited our possibility for a lot of the fun excursions and a rainy day for CC. We did two short beach days on our own in St. Thomas and St. Martain. Not to say the 7 day isn't great, if you can afford it, why not, just a different perspective.
