Yes, you can absolutely walk from the Walt Disney World Dolphin Hotel to EPCOT, and it is considered one of the best "perks" of staying in the EPCOT Resort area. The walk is entirely scenic and takes approximately 10 to 15 minutes at a leisurely pace. You simply exit the hotel toward the back (the lake side), walk across the bridge toward Disney's BoardWalk, and follow the paved pathway that runs alongside the water. This path leads you directly to the International Gateway entrance of EPCOT, which is located between the United Kingdom and France pavilions in World Showcase. This entrance is typically much less crowded than the main front entrance of the park. Along the way, you'll pass the BoardWalk's shops and bakeries, making it a very pleasant stroll. This walking path also provides easy access to the Disney Skyliner station, allowing you to quickly travel to Disney's Hollywood Studios or other resorts if you choose. For many guests, the ability to avoid buses and monorails by simply walking to the park is a primary reason for choosing the Dolphin or its sister hotel, the Swan.
