We stayed at this hotel last week and were really pretty happy with it. As far as transportation, the bus was only really full where we had to stand on two occasions during the 5 days we were there. Also, this was during spring break when all the DD hotels were booked, so I thought this wasn't too bad.
Yes, the buses do make stops at other DD hotels to pick up people, but they wouldn't be so full if people from hotels offsite wouldn't come in and park at these hotels and take the buses. This really wouldn't bother me so much, except for one of the times we had to stand, my son was sick with a fever and wanted to sit down. I am also almost 8 months pregnant. So there I am, with a sick child asking "Mommy, we have to stand?" very obviously pregnant, and this one guy sitting in a seat right behind me is bragging about how he is staying at a hotel outside DD and he is using their transportation. It crossed my mind to make a sarcastic remark, since I was probably paying more for my hotel room than he was, and had a legitimate right to a seat, but we were usually the first hotel to be dropped off at and picked up, so I didn't say anything.
The buses do take you to the TTC to be dropped off for Magic Kingdom, and have an assigned parking space in a lot where they drop you off and pick you up. This walk wasn't so bad, and was better than driving our rental car, parking, getting off, etc. The buses ran every thirty minutes and were very timely.
Since my husband and I both have Gold Hilton Honors memberships, we got access to the concierge level for a continental breakfast in the mornings. Also, you could get water at no charge to take to the parks, rather than buying it inside the park. They had hors'dourves (sp) in the evening (shish kebabs, egg rolls, cookies, etc) and soft drinks. The hotel was full when we checked in, so they told us they couldn't give us an upgrade to a bigger room. Our room wasn't ready yet, but when we came back 30 minutes later and got to our room, we were very happy with it. It was a corner room, with two big windows and was actually pretty spacious.
So, basically, we were pretty happy with the Hilton.
