I thunk GCH is a better overall RESORT. It has everything. DLH is a very nice hotel with a great pool, but it's lacking in dining options, grounds, and a place to sit and relax indoors. The one bar is very hard to get into and the walk up has long lines often.
The GCH has that amazing lobby, several dining options, including late night dining at Hearthstone, two bars to choose from, a spa, and better overall service. Plus the location cannot be beat.
The beds are identical at both and are SUPER comfortable. However, the bathroom setup at GCH is better for privacy.
