Welcome to planDisney, Mona!
Wow, I can not imagine how wonderful it must feel to be heading back to the Happiest Place on Earth.
Mona, other than a few special circumstances, you will not need to enter the park with your guests. Just make sure that each party member has their
own ticket that is linked to a valid
theme park reservation for that day.
Now, if you have purchased specially discounted tickets, such as military tickets, you will need to be with your party in order to activate those tickets.
I hope that this answered your question, Mona!
Enjoy your magical day!
