Welcome aboard, Julie! How exciting! If it's time for you to book
Port Adventures, that means it's almost time to set sail!
Disney Cruise Line does allow guests to book more than one adventure on the same day in port if the two do not conflict. When you log into your reservation once your booking window opens, you'll be able to see the start times and lengths of each adventure. Some adventures offer multiple times to choose from. I suggest booking your "must-do" adventure first, then check out the others to add to that day. If there is a conflict, the booking system will not allow you to book the second, to be sure you don't miss it because of a potential overlap with the first adventure.
Do keep in mind that adventures can run a little behind based on factors beyond their control like weather or traffic, so allow as much time as possible in between. Meeting spots for the adventures are typically onboard the ship where you'll meet your group and walk off together to your transportation.
I hope those details help as you get ready to book your exciting Port Adventures, Julie! Have fun planning!
