HELP!!! I am in great debate whether or not to switch my 4 night to a 7 night. I have found a great deal on a 7 night Disney cruise that would be affordable for me. It is also very close to the original date we already had booked. The only big difference other than the extra nights is we are going from a cat.10 sph to a cat 11. I first chose a 4 night because we have never cruised and wasn't sure how we be with sea sickness and all. No one gets motion sickness but I know it is different on a ship. Would you suggest a shorter cruise for the first time out or just go for the Shabang?
I wouldn't hesitate doing the 7 especially if there isn't a large price difference. As others have already said...no one has complained they should have done the 4 instead of the 7 day! I say go for it!

Book that 7-day already! It will definitely be worth it!
