Hi T!
It would certainly be possible to walk-in to Downtown Disney's
Paradiso 37 for drinks and appetizers. Whether you are on a Disney Dining Plan or not, you're welcome to enjoy as little or as much as you'd like to order here ... and I HIGHLY recommend it! I had the pleasure of trying this restaurant just last month and it was fantastic. I can hardly wait to return again.
This location is open for both lunch & dinner and the time in between, so you should be able to relax and have some snacks and a beverage at whatever time suits your schedule for the day. If you know roughly what time you'd like to arrive, it certainly wouldn't hurt to make yourself a
reservation online in advance, and you don't have to be on a Disney Dining Plan to do so. Keep in mind that Disney's table service restaurants are popular spots and often do reserve in advance.
Thanks for visiting the Moms Panel and we hope to hear from you again soon.
Enjoy your afternoon at Downtown Disney and I hope you have a relaxing time at Paradiso 37!
