We did not attempt. I’ve heard you need to show your room key to enter and we didn’t want to chance it. I’m sure you could try to piggyback with someone else who is entering. Not sure how strict they are in the mornings.
Plus, when we stayed at the grand last year, the security line to enter into DTD to walk to
Disneyland was insane! I feel like walking the extra distance to the DLH security entrance would be faster. I’m sure it depends on the time of day as well. But I think they only have 2 or 3 metal detectors to enter DTD from the grand. It was slow going.
Have fun on your trip at homewood!
