You can get your ticket scanned at the DTD monorail station. It is next to Rainforest Café if I remember correctly. You get in line, they do a security bag check then you go up the stairs ( Or take the elevator) to the platform to wait for the monorail. We used this entry a few times when we were staying at the DLH and loved it. It can get crowded though depending on what time you want to go. A couple of times there was quite a crowd, so we opted to walk to the Main entrance. We enjoyed the walk through DTD. The music, the stores, the smell of yummy food from the food carts/ restaurants etc. and it only was about a 5-7 minute walk.
