It's possible, but we probably won't stay til 12 am! Even with Paul sleeping in the stroller, DD is only 8 and not really a night owl! I kind of thought maybe we'd let them run around til 9 or 10 and then take them back to the resort, and maybe DH and I would run back out together just the two of us while the kids crashed out with grandma and grandpa.
The kids tend to be early risers (read 6:30 on the weekends...4:30 for DS this past weekend!) I am not saying the plan won't change, but at least it's a start!
