We can't decide between the 28th and the 30th. We will be there all both days, but won't be staying onsite until the evening of the 30th-which might make getting to and from the MK easier-especially with 4 kids. My parents have a timeshare and we are splitting the trip between there and the Contemporary. Since we are driving from Oklahoma and not arriving until late Sat., we are still debating whether or not we would be too tired on Sun. to go. In the last couple of days, we have started leaning towards Sun. night instead of Tues. night, but we haven't bought tickets yet.
