For us, it's just not worth it. You can stay in a good hotel across the street for $200/night less. Honestly, if I had the extra $1000-1500 to spend at a
Disneyland hotel, I'd probably just spend a little more and fly to WDW and stay at one of their moderates. In my opinion, mine, the moderates there are better than the PPH or DLH. And the Grand Cali is like the Wilderness Lodge, which is the low end of the deluxe at WDW. But at DL, it's like the premium of all premiums.
But that's just how we do it. We have stayed at DLH at a huge discount, and even at that price, it was barely worth it for us. But I think everyone should try it at least once.
