The one next to the convention? The shuttle will stop at that hotel as well, but you could also walk. Here are the directions for walking, it may sound a little confusing, but it'll make sense when you there and you'll see others walking as well.
Try to come out of the hotel on the Katella side. You'll be facing the back end of DCA. Turn left on Katella and walk towards DL Drive/West Dr. It's the street that the resort hotels are on. When you get to DL Drive/Katella crosswalk, cross the street so you area on the same side as the PP and turn right. You'll be walking towards PP. This is where it starts to sound weird, but I promise it's not. Once you pass the PP, there will be a parking lot. You can either turn left and cut through the parking lot to the service road and turn right to walk down the service road or cut diagonally through the parking lot to the service road. When you get to the parking lot, you will be looking/heading towards the AMC movie Theater at the end of DTD and the DL hotel. When you go to the expo, if you go to the DLH from DTD, you will see the service road I'm talking about. It's also the last bit of course that we run down to the finish. The staging area is in the DL hotel parking lot. I know it sounds confusing, but it's really not. Plus you'll see tons of people walking and there will be music coming from the staging area so you know you're going the right way. If you walk instead of the shuttle, it'll be about a mile walk.
I did up a map so hopefully it'll make sense!

:
Map my run map. You can make it larger to get a better sense. Just a note though, when you look at the map, where you turn left into the parking lot, the hotel across the street is the GC, not the DLH like the map says. The towers shown at the end of the route make up the DLH.
