Welcome to planDisney, Joana!
In a few days' time, you'll be driving through that famous archway and arriving at
The Most Magical Place on Earth. I can only imagine how excited you are, right now. Joana, you're going to adore staying at
Disney's Pop Century Resort! Make sure you take some time during your visit to stop and enjoy all the nostalgic tokens around this hotel. I just love how all the oversized toys make you feel like you're in a real-life Toy Story. You'll also have easy access to
Disney Skyliner too! Although I'm not the biggest fan of heights, this is actually my favorite way to travel at Walt Disney World. It's so efficient and comfortable. The Skyliner will take you to the International Gateway entrance of EPCOT (close to the France pavilion around World Showcase). At the end of your day, you can hop back on Disney Skyliner from the same location and travel back to your hotel.
Joana, since Disney Skyliner takes you to EPCOT, buses do not run from Disney's Pop Century Resort to these theme parks. However, if you would prefer to take a bus rather than Disney Skyliner, then you might be helped to know that
Disney's Art of Animation Resort offers bus transportation to the front entrance of EPCOT. If you cross the small bridge that connects the two resorts over Hourglass Lake, then head straight through the main lobby at the front of Disney's Art of Animation Resort, you'll find the buses. You can then jump on a return bus from the same location at the end of your day.
Side note: if Disney Skyliner is temporarily shut down, Disney will provide bus transportation to and from Disney's Pop Century Resort. This happens when there are technical difficulties or inclement weather.
I hope that's helpful, Joana. Have a wonderful trip!
