We love the Boardwalk Inn!!! The rooms were soooo comfortable - the beds, pillows, bedding - seriously to die for. Being able to walk to both HS and Epcot was wonderful. The walks are so easy that I wouldn’t even bother with the boats. They take so long - stops at BC/YC/Swan/Dolphin.
We had a room right off the elevator, so long hallways weren’t an issue. We had a standard room so the view wasn’t anything great, but that didn’t bother us.
Some people are freaked out by the “clown pool” but DD loved the slide and CM’s did many activites by the pool during the day.
The only counter service is the Bakery which is actually on the Boardwalk, not inside the hotel. We went there for lunch one day and for snacks (cupcakes, etc). We had a grocery delivery so we ate most breakfasts in the room.
The only real negative is it’s a pain in the butt to get to MK and AK. The buses really took forever from the BWI and many times share with other resorts.
So if you’re planning on spending most of your time at Epcot & HS I would say that there are no negatives! Enjoy!
