Hi Claire!
Welcome to planDisney.l
Yes, you are correct that Disney Skyliner will be closed for routine maintenance from 16th January. But you are also correct that there are other ways around this so you can arrive at EPCOT via the International Gateway entrance.
It's a good idea to take an Uber or Lyft ride to one of the EPCOT Resort hotels when making your way to International Gateway. I have used Lyft myself and enjoyed the efficient service. I downloaded the Lyft app which gives you a selection of available cars (with prices and varying pickup times). You make payment on the app before your ride, so it's straightforward.
I would opt for Disney's Beach Club Resort as it is the closest, but Disney's Yacht Club Resort is not much further away. Both Resort hotels are only a short walk from International Gateway, but all EPCOT Resort Area hotels (including Walt Disney World Dolphin Hotel and Walt Disney World Swan Hotel) are served by FriendShip Boats if you have time for a relaxing boat ride.
This map shows where the hotels are located in the EPCOT Resort Area - you'll need to scroll down the page to find the map.
If you would like to upgrade your ride, you can also order a
Minnie Van via the Lyft app.
If you are planning to explore all of EPCOT from International Gateway right up to the front entrance you can then take a bus back to Disney's Caribbean Beach Resort at the end of your visit. Buses will be available for all the Disney Skyliner Resorts to/from all four theme parks throughout the Skyliner closure.
Please come back and visit us if you have any further questions, you can also
send me a direct question if you wish. We will be very happy to help you plan your magical vacation, and keep your eye on the
Disney Parks Blog for all the latest official news about events that may be happening during your stay.
