Planning a trip for 4 or 5 nights.....not long I know, but it's all we can manage. Arriving on a Thurs evening, departing Tuesday evening. My plan is to stay 2 nights at WDW and visit MK Friday and most of Saturday. Then change to Universal Saturday night and enjoy Sunday and Monday - leave Tuesday. Thoughts? Also, what is the easiest way to go between the two - simple cab ride or are there regular shuttles? Thanks for the help.
