Well its always nice to have Early Entry each day its offered. And the nice, themed pools offer a nice break when the parks are crowded. But you can sitll have a great time at DL and actually be closer to the parks staying at one of the offsite motels on Harbor. I think dining reservations will be okay as long as you make them soon. Full service dining at DL is not as big of a thing as it is in WDW. But I wouldn't wait too much longer. The real deal will be what kind of rates you can get onsite, (or offsite for that matter) if you an even get a room this close to your busy travel time. The three onsite hotels at DL almost always sell out on the weekends and that makes getting good deals or reservations in general hard to come by. If they don't have any rooms left be sure and check Expedia and Hotels.com, sometimes they have rooms when Disney doesn't. Good luck!
