BW stovall is our go-to hotel, we have stayed there several times and just recently in May when I ran Tinkerbell! We haven't had any issues other than our last stay the Wi-Fi wasn't working (all 7 days) and we had to purchase a data plan (we are from Canada) so hubby could do some work in the room, they gave us a credit back to cover us having to purchase the data plan!
for breakfast I typically go down, get what we need then go back up the to room to eat -- the eating area can be a zoo and I prefer not to bring the entire family so we can get ready at our own pace while enjoying breakfast!
the distance to the parks is slightly longer now that you can't get in thru GCH but that is more than worth is when it comes to security checks! we have never waited more than 10min to get thru security between earl of sandwich and ESPN, i have seen and heard the lines on the harbor side can get up to 25+min on busy days! I'd rather spend the time walking thru DTD or taking the monorail into the park vs standing in the harbor security line -- JMO!
on our way back to the hotel after the parks we all ways cut thru GCH either by going thru the turnstiles across from grizzly rapids in DCA or thru the breezeway after Sephora!!
