Hi Melissa!
Disney's Coronado Springs Resort is my favorite moderate Walt Disney World Resort hotel! I love the decor of the entire property and it's beautiful to walk around the lake, especially at night. It would be a great resort to surrey bike around, however, I did call the Resort hotel to confirm that surrey bikes are not offered as a recreational activity at this time. After doing a little researching, I did find out that they were offered in 2016, but I am not sure how long there were there or when they stopped.
It's possible that the map you are looking at is outdated. If you do a Google search for "Disney's Coronado Springs Resort Map 2019", you'll find the newest maps that include Gran Destino Tower, which just opened in July of this year.
If you're still interested in
renting a surrey bike, consider heading over to
Disney's BoardWalk. You can access the BoardWalk from the International Gateway entrance/exit of Epcot, so you can add it to your park day if you need a break from the park. The ride is fun and pretty along the lake and afterwards you can grab a delicious ice cream at
Ample Hills Creamery or a sweet treat from the
BoardWalk Bakery.
Please stop back by if you have any additional vacation planning questions.
Have a magical day!
Leslie
