I'd advise you to price it out yourself to see the difference. Be aware that the "Good Neighbor" designation means nothing-- those hotels just paid Disney a price up front to get that designation; it doesn't mean it's a particularly good property.
I've always managed to save a bundle by booking directly with the hotel, using whatever discounts I can (this year I'm eligible for AARP, gulp!), and getting tickets through whichever authorized reseller has the best deal. Lately it's been LastMinuteTravel (LMT... they supposedly have a $50 a year membership fee, but the discount codes that waive the fee are easily available if you google it). They were beating
Undercover Tourist by around $30 per ticket for 5-day-parkhoppers when I bought them last month.
Edited to add: out of curiosity, I did just this: I looked at what Disney would charge for a good neighbor package including 4 day parkhoppers and a close good neighbor hotel-- they showed Camelot, which is one of the ones near the crosswalk. I put in March 4-7th, and got a total of $2175. Then I compared. It wasn't easy, because the Camelot website isn't showing availability into next year yet, so I substituted early November, and got a price per night of $149 ($10 less for AARP,
AAA, or military). The
Disneyland price works out to $231 a night. Although, the $149 doesn't include taxes and resort fees, which seem to add up at the final bill. Also, I went to find tickets at LMT, and they aren't showing Disneyland tickets at all right now, which is weird. So I went with Undercover Tourist and got prices for a 4-day parkhopper as $333.95 for the kids, $350.95 for the adults. (that compares to Disney standard pricing of $360 and $380). Bottom line: the Disney package costs $2175, but you can likely get the same package for around $1920., booking it yourself-- a savings of $255. Even if they give you a resort gift card or a meal or whatever, it works out better.
