We are spending 3 1/2 days at the parks, half day on day 1 at MK, day 2 at HS, day 3 at Epcot and day 4 at MK. Trying to decide if we should do the BBB on the first or second day or do it as a grand finale at the end? Not sure if the hairdo will prevent swimming (meaning the girls won't want to get it wet) so it would be better to do it the last day.
