This trip, the Grand Californian Hotel & Spa was our home for 3 nights. I loved, loved, loved the craftsman architecture, the woodsy (very California) decor with tree accents, the humongous brick fireplace in the lobby, the family centered feel (milk on ice and warm cookies awaiting our arrival!), coloring activities for the kids in the lobby while we parents had a glass of wine, and the easy park access (you are right in Downtown Disney and you can also walk right into California Adventure - no ticket line). I didn't get a chance to try out the spa, but for us it is all about the kids when we go to Disneyland. Maybe when they get older. Bunk beds with a trundle bed underneath worked perfectly for our family. I almost want to get a trundle bed for Ava to put under Ben and Lily's bunk beds at home and turn Ava's room into my office! I would stay there again in a second.
NOTE: I heard from the Disney team that Disneyland Hotel is getting a major renovation starting late this summer. They will be doing it in two stages, so that the hotel will be available during renovations. There are some outdated parts of that hotel, so its great that they are redoing it.
(FULL DISCLOSURE: Disneyland footed part of our bill for our trip, as I was covering the Macy's Moms event. Disneyland doesn't do this very often at all, but it was just the perfect opportunity since our family was already headed to the park this particular weekend anyway.)
