Hi there, Patricia!
You made a wonderful decision to have dinner at
Topolino's Terrace at Disney's Riviera Resort. While I haven't had the opportunity to have dinner there, I can only imagine how spectacular the views from the restaurant are at night.
Patricia, while the
Disney Skyliner and
water taxis generally run-up to an hour after the theme park has closed, you will want to drive your car to your dinner reservation.
When you exit the theme park on the water taxi, or towards the Disney Skyliner station, you will exit through the back of the park, through the International Gateway. Since the parking lot is located at the front of the theme park, if you are done with dinner after the theme park closes for the night, there is a good chance that you will not be able to get back to your car. So, if you are not having a super early dinner, to avoid any stress on your part I would recommend that you drive.
I hope that this answered your question, Patricia. Please come back here if we can help answer any other questions for you.
Happy noshing!
Sarah B.
