I don't know how far exactly the DTD entrance from GCV is to the
Disneyland gate but I would guess that if you recall seeing the Disneyland Hotel tower that is closest to DTD, the GCV entrance to DTD is just about half way between that tower and the Disneyland Park gate.....right in the center of DTD. The counter service restaurant is White Water Snacks. I love it too. They are expanding it to include the grocery type items that all
DVC properties have. Let us know if you do your add-on!!
