Hi Veronica!
Congratulations on your upcoming vacation to Walt Disney World! The outdoor seating at the
Rose and Crown Pub is a fantastic and very popular place to watch Illuminations. A patio table can be requested, it is not a guarantee and the closer it is to Illuminations the harder it is to secure one of these highly coveted spots.
I think that you will possibly have time to reach Epcot to view Illuminations, this can depend on several factors such as the front desk line at Pop Century. I would recommend checking in and immediately head for the bus stop area just outside of the main hall to board the bus to Epcot. If you are able to reach Epcot by 7:30 pm, your chances of catching a patio table at Rose and Crown will probably be pretty good.
La Cantina de San Angel is another great outdoor counter service option to view Illuminations, if the Rose and Crown Pub is not available.
Tokyo Dining is also a good option and is usually easier to reserve a table at this location. There are no tables outside however, but the windows offer some spectacular views of Illuminations.
I hope this helps and please let me know if you have anymore questions!
Best Wishes!
Mandy
