We have never been to Disney on the 4th. Could use some advice and info. We are planning to see the fireworks at MK. We would like to make ADR at Plaza for dinner but I know the park usually will max out at some point and we dont want to get shut out. I heard that if you have a ADR in the park they will still let you in. True?? Do we need to make it an early dinner? Any "must do" on the 4th would also be appreciated.
