Hi there, Michele, and welcome to planDisney! You'll be arriving at the Most Magical Place on Earth tomorrow, and you must be so excited! Thank you for stopping by with this great question as you finish packing your suitcases.
Michele, it sounds like you're hoping to start your EPCOT day strong with some thrilling attractions - you'd fit right in with my family! In my experience, the
Single Rider line has not been open during
Early Theme Park Entry. Happily, you should be able to get a great spot in the queue for
Remy's Ratatouille Adventure by arriving early. This will be easiest if you're using the International Gateway entrance, rather than the main EPCOT entrance.
While everyone's experiences during Early Theme Park Entry will be different, here's how it worked for my family: we left our room at Disney's Beach Club Resort around 7:30 am, coffee and breakfast in hand. We walked over to the International Gateway entrance of EPCOT, went through the security checkpoint and tapstiles, and stood in a queue where the Cast Members verified that we were Disney Resorts Collection hotel Guests. By 8:00 am, we were walking across the bridge toward the France pavilion and the Remy's Ratatouille Adventure queue. The attraction opened on time at 8:30 am, and we exited Remy's Ratatouille Adventure about 20 minutes later. We opted to head toward
Soarin' Around the World and Living with the Land at that time, but going toward
Frozen Ever After would have been a solid choice as well.
One other piece of advice I'll give you is to keep an eye on the My Disney Experience Mobile App as you go about your day. Attractions can close temporarily due to unforeseen circumstances, and that can really alter your strategy, since Cast Members are generally unable to share how long the delay will be. It will be up to you to decide whether to remain in that queue or head toward a different attraction (it's always a tough choice).
Michele, I hope this is helpful to you as you plan your day at EPCOT! Please stop by planDisney with any other questions you have!
See ya real soon!
