It truly is "Grand." Definitely the nicest hotel near the park and probably one of the best overall hotels in Orange County. The best being the St. Regis Monarch Beach and the Ritz-Carlton Laguna Niguel...but they're even more $$$ than GCH and you can't walk to Disneyland from them!
The architectural and decorative details of GCH are astonishing and they really did a nice job with the theming. Be sure to take advantage of the perks offered, such as early entry to Soarin', free architectural tour, and the morning fitness walk thru DCA (if you're into that sort of thing).
The common areas are more impressive than the guest rooms, which are a bit on the small side. I also thought the bathrooms were just OK (small tub and not particularly luxurious materials), especially compared to other newer 4- and 5-star hotels. But the convenience of being so close to the action of the parks and DTD more than make up for these minor shortcomings. I'll be there in less than 2 weeks. I'm so excited.
I'm sure you will be DAZZLED. What a great birthday present!
PS: Any MCers been to the new Mandara Spa at GCH? Mandara is considered one of the best and has locations throughout the world. But it seems really expensive, even by Disney standards. An 80-minute massage, with a mandatory 18% gratuity is $224.00. A 50-minute facial is $177.00. Together, that's another night at the GCH...with a theme park view.
