First of all, let me say I've never been there, but am in the planning process myself.
DH just said this afternoon that he's convinced that we should stay at GCH.

I am a Disney nut, and when we started planning this SoCal trip, we initially thought we would stay some place on Harbor like Embassy Suites b/c we like r-o-o-m, and we're going to be in SoCal for a week.
We had it narrowed down to Embassy Suites South, Hampton Inn & Suites and Doubletree Suites (see the theme?), then Disney announced their 5 for 3 deal. We priced out
Disneyland Hotel, and it was just a bit more than these hotels for the same time period, but after a lot of research, we decided we didn't want to stay at DLH this go round. We weren't interested in PPH at all. That left GCH. The package for 5 nights at the end of June/start of July for our family in a standard view room at GCH + tickets is going to be a grand total of just over $2200, which is about $600 more than Embassy Suites.
Hmmm.......
This wasn't as bad as the difference before the deal was announced, and we started asking ourselves questions. How much value and utility can we get out of an extra $600? If we book through Costco, we can also get a $20 gc and vouchers for a premium character meal. That is definitely of value and will save us money towards the price difference. The package also includes a 5 day PH for the price of a 3 day, so we get a few extra days if we wish! We like Disney quality and ambiance, and frankly, even at rack rates, GCH isn't as expensive as what we've payed for rooms at WDW over the past few years, it's just that we're doing more than Disneyland. We understand that Disney commands a premium price, and we're not getting a room comparable to the Ritz. We know that the kiddos will enjoy staying at GCH more than an Embassy Suites that's basically identical to the one they stayed at in Atlanta a few months back. We love the idea of being close to the action and not at the mercy of ART. This is our first DLR trip, and who knows when we can go again. Even though we'll not even be at the parks on two of the days, it's still fun to think about staying at GCH anyway. And most importantly, the $$ is in there. We're not going to not pay a bill, go in to debt or get in a world of hurt if we upgrade - still cheaper than the
Disney cruise we considered!
Sorry this is long, but having had this same conversation over the past few days, I wanted to share our process!
