Nick and Cindy,
I answer to your questions:
1. For our first cruise with kids we felt the 4 days was about right. However, our kids just started to develop relationships with other kids on day three at sea. Our kids are 10,14,15. We wanted to give everyone a "taste" of cruising to make sure we were comfortable with it. We have talked about making the next cruise a 7 day but are not fully decided on that. For our purposes, the 4 day was great.
2. Our cabin # was 8084. This was a level 4 family stateroom. We were amazed at how well this room accomadated us considering we are used to renting 2 bedroom condos when we travel. TIP: take along one of those over-door shoe racks to hold all bathroom items. I think it saved the day!The cabin was just below Beach Blanket Buffet and provided some chair noise about 6am but we still loved the location close the the top decks and just down from the aft elevators and stairs for convenience.
3. Seasick? The seas seemed roughest the first night. Although nobody got seasick there was motion the first night. I felt Meclizine and Dramamine taken before the motion started prevented any potential problem. I actually felt worse when we reached land again. The ground is still moving.
4. Flight night before? Yes and we would repeat. We had an evening flight arriving at 8:30 pm and stayed at Embassy Suites. The rate was $79 with full breakfast for a 2 room suite. The hotel was beautiful with some good family restaurants within walking distance.
Hope the helps , Dave and Kim
