Yes, it's best to eat before you go although you can enter the park at 4:00 for the party so there's plenty of time to eat between then and 7:00. Must do activities depend will depend on who you ask. For me it's the fireworks and the later parade, riding Haunted Mansion and getting the special photos ie. with the hitch hiking ghosts, since it's only avail during the parties. Other people are big into the meet & greets with special characters and regular characters that are dressed for Halloween. There's a lot to do, it's hard to work it all in. There is also a special show at the castle and special treats. I personal bypass the trick or treat stations, I can buy candy at home lol. It's by far my favorite party! The fireworks are WAY better than regular wishes IMO and I love love love the headless horseman and haunted mansion characters in the parade.
