Lastminutetravel.com bookings are cancellable..check the rate rules for each hotel...so no downside there. Sometimes it's good to have a cancellable backup while you investigate Priceline or Hotwire. I didn't look too close at 3 or 3.5* properties on LMT, so don't know what's available there. A lot of people book the Howard Johnson's on Harbor via the Entertainment Book rate...how cheaply I don't know. I've stayed at the Hilton before. It's a very large "convention" hotel, but we found it walkable to the parks, or you can take ART. Don't know much about the Marriot. Regarding internet, when we stayed at the Hilton, we were able to connect up via the hotel next door, so no internet fee. If you don't secure your signal, never can tell who might hook up to your network. Good luck.
