Our first trip was 4 years ago and yes, it has changed a LOT since then. We were right at the end of the park not being busy phase as we first visited in March of 2012 before Cars Land opened in May. We had days that were so empty - we would look at ride times of 20 minutes and be like "who waits for that?". Then we returned in May of 2013 after Cars Land had been opened for a full year almost and man, a LOT busier. Sure it was a bit of a busier time but California Adventure all of a sudden had a bunch of people in it - what was up with that. And of course the recession, or whatever you guys had was over, and the prices started creeping up. Our first visit we paid about $175 for the kids suites at HOJO with our
AAA rate and this year going the exact same time it's $233. We had AP discounts our last two trips as we bought an AP to cover across two trips. It has gotten a lot busier and we are bracing ourselves for it.
One of the big changes is FP return times - you can no longer get a FP and then take your good old time to use it - you have to return within the return time window - I have seen people turned away for trying to do this. There are also a fair number of closures around the Rivers of America area in DL which are ongoing for about a year or more to make room for renovations to add a Star Wars land. Star Wars has meanwhile pretty much taken over Tomorrowland in the mean time although not sure how long that will all last. Buzz Lightyear has a FP now, if that doesn't say it I don't know what does!
So if you are planning to be in the parks for 5 days, with a family of 4 all of which have to buy adult tickets then you are looking at $1260 in tickets - however, there are places to buy discounted tickets but the lowest I have seen is maybe saving about $30 a ticket. Then if you are planning to stay for 7 nights, that leaves you needing to find a place to stay for about $165 a night including parking. That is without any food factored in. I honestly don't know if I'd agree that $2500 is doable. But heh, you are not coming from Canada so count yourself lucky for that. Right now our exchange rate is adding close to 50% onto the price of our hotel, car rental and food! This trip staying 8 nights at the Hojo in the kids suites, renting a car through Costco and buying our tickets in CDN dollars discounted is over $5000 CDN and that is before we buy any meals or add the cost of our flights (which were a smoking deal which starting the whole idea of returning). Disney is no longer a cheap holiday but we absolutely love it!!
Still the good news is there are so many people here that have so many great ideas and advice so just roll up your sleeves and dig in and before you know it you will be much more at ease planning your trip!
