Yeah. We were on that damn boat so long, in the heat & humidity, that by the time we stepped into DHS we both were having a bout of heat stress :ack:, and had to stop at the Medical Station before we passed out. A couple of ibuprofin and we were good to go again.
...I dunno, the walk from Epcot to DHS seems longer than the CBBR to IOA walk. It's not a complete straight shot if I remember correctly.
