We have done back-to-back twice now and have a three-peat scheduled for this year and another two-peat scheduled for next year.
If you like 7 days, you'll love 14 days. We'll let you know what 21 days is like when we get back in Sept. The problem here is trying to figure out what else to do during the year with the rest of our vacation time.
We have always kept the same cabin. We will always choose to stay on board when allowed (must go to the 'custons' talk on cc day to find out if you can stay on or not). We usually do laundry, hang out at the pool, 'check-in' at guest services, do the ressie scramble and have a bottle of Fairytale to celebrate vacations. Sometimes we check out other cabin catagories for future information.
