Just know that you cannot cut through the GCH on the way to DTD and the parks, but you can cut though on the way back from DTD to Disneyland Dr. That can be a very welcome and scenic shortcut at the end of the day.
No, if you are referring to the Hotel Indigo across from the Walgreens, look on Google Maps and you'll see that Harbor is much closer than Disneyland Dr.Would this also be a shortcut if you’re staying at one of the hotels on Katella like Hotel Indigo?
