We have been on 6
Disney Cruise (2-three nights, 2-four nights, and 2-seven nights). We have 11 year old twin girls, and they love the cruise!
We have decided we like the 4 night the best because we like to go to WDW also when we vacation, but if you have decided not to go to WDW as well, the 7 night is heavenly! I really don't think you will be sorry if you do a 7 night. If you want to try the shorter one first, the 4 night is MUCH better than the 3 night for a couple of reasons:
1. It is the only one of the cruises that has the option to dock at
Castaway Cay on two different days if the weather is bad (the 3 & 7 night cruises go to CC on the last day, so if it isn't good weather and they can't dock they have to return to Florida the next day).
2. It is the only one of the cruises that gives you a day at sea AFTER visiting Castaway Cay. That way, on your last day on the ship, you can take your time packing and not feel rushed. On the 3 & 7 night, you have to pack up the evening after leaving CC, so you are tired from your day at the beach and then you have to rush around to get packed up that evening.
3. Since you have an 11 year old, you may be going to the Final Farewell Kids Show (some kids decide not to do it, but my kids never miss it). On the 4 night, the show is held on the last day, which is a day at sea. On the 3 & 7 night cruises, the show is held on the last day which is your day at CC. SO you have to leave CC and go back on the ship and have your child clean up to go to the rehearsal which is about 1/2-1 hour after boarding time for CC (we always leave CC early to get back to the room to clean up the kids, but on the 4 night, since the show is on the last day, we didn't return to the ship until the boarding time).
We like the 4 night, also, because we can drive to it. We have a 17 hour drive to and from home, so we can take a 1 week's vacation and still have time to drive (leaving Friday night after work) to Florida and be there in time for the cruise on Sunday (the 7 night cruise leaves on Saturday, so we don't have time to drive there) and we return over the following weekend after spending 2 days at WDW (the 3 night ends on a Sunday, so there isn't enough time to drive home from that one).
Anyway, all of the cruises are nice, no matter which one you pick, you will have a wonderful time!
