Last summer I stayed on points at both the GC and DLH. We also had the view over the entrance to the hotel and the parking lot across the street at the GC. We got the Sleeping pad and sleeping bag they have instead of rollaways. Needed three beds because the group was me, my son age 15, daughter age 34 and grand daughter age 14. While the access to the parks was great at the GC the room at DLH was much better for us. It was bigger and there was a day bed as well as the two queen beds and it even had a dorm size fridge and wet bar. I had requested a rollaway, before I knew about the day bed, which was also there and we had them take it away. ( It was no charge if we used it unlike at BWV at WDW where it was $15 a night). The GC had a mini bar with a space that would hold about 2 sodas as your personal space and very pricey items if you chose to use them. If I go back I will definitely use the DLH and ask for the pool view. We were on one of the upper floors and had a great time looking out at the wedding area and the pool area. We went to the pool at the Paradise Pier and had a nice time when the pool at the DLH was closed for chemical correction due to people allowing their small children in the pool without swim diapers. The paradise pier had a good view of the fireworks from the pool area. We really didn't get a look at any of their rooms so can't help your there. All in all they all were nice and it really wasn't that big a deal to walk to either of the parks. You can use all the pools so that waasn't a consideration as the walk is short between the three places.
Hope you have as good a time as we did - For me it was a trip back in time as I lived two miles down the street from the main entrance from 1955-1958 and had been there for the pre opening invitation only trial days in July 1955. We used to watch the fireworks from our back yard back then and it really was a "trip" to go back.
