I'll confirm that, that the only Downtown Disney resort that seems to have made the deal with Disney for early entry and guaranteed entry is the Hilton. If those are important to you, you might want to consider the Hilton or a Disney-owned resort. However, with that said, the Grosvenor is in a very good location, easy walking to Downtown Disney, and I hear very few complaints about it. Some of the rooms are exterior access, and while that doesn't matter to me, if it matters to you, you might consider that when making your choice as well.
