Sunday is a fun day. You can go into a park or go to Disney Springs.
Did you know that House of Blues does a Sunday Gospel Brunch? It certainly does on Sunday from 1030 AM to 1 PM.
It is an all you can to enjoy meal and reservations are HIGHLY recommended. You can call 407-934-BLUE.
This is something fun and different to try.
As for a park, usually Magic Kingdom is a good choice. Either way enjoy your day!!
