On our trip with my family at the end of September last year, we enjoyed a pre-park opening breakfast at Garden Grill. If you're looking for a way to ride both Soarin' and Test Track or Frozen with little wait (all three are tier 1 attractions at Epcot, and so only one can be booked), snagging an 8 AM breakfast at Garden Grill when Epcot opens at 9 AM is the best way to do it. Besides giving you access to Soarin' before the rest of the crowds make it in to The Land Pavilion, you'll also enjoy one of our favorite breakfasts on property, and one of the few dining experiences we think is worth the cost for the characters, food, and ease of ride access you're paying for. Let's look at what you can expect with an early breakfast reservation at Epcot on a 9 AM opening day:
We arrived to the bag check at Epcot at 7:36 AM for our reservation. When I made the reservations 180 days out, there wasn't any availability for 10 people whatsoever, so I split us up (this is a great trick for finding large party reservations!). We had Garden Grill reservations for 6 people at 8:05 and 4 people at 8:10.
As you can see, there were very few people in line at bag check when we arrived. They did not begin checking bags until 7:42, and we were through bag check by 7:45.
