Bill - As others have said, this is a great summary.
Do you mind elaborating a little on the last point - "Expect to spend more on Disney vacations after you buy DVC"? Not questioning it at all, just looking for some more detail. Thanks so much!
I'm not Bill -- but I'll attempt to answer for him, since I am an extreme example of what he is talking about.
My original plan was to go to Disney once every 3 or 4 years -- anything more than that (I reasoned), was wasteful and the kids wouldn't appreciate it. We went on a cash reservation in February 2016 and had a blast (DD2, DD<1). I got hooked and decided to look into DVC.
I convinced DW that instead of every 3 or 4 years, with DVC, we could go at half price and therefore go every 2-3 years. (more often means more travel and food costs)
I figured 150 points would get us a studio for a week every year -- so that's what I focused on.
We then got a contract accepted, and it came with a lot of extra points. Then I was like, "hey -- we can afford these 2 BR units if we bank/borrow, let's bring each set of GPs on a trip so we can all enjoy it together!" (more money)
Then I figured that if we were going to do the GP trips, we should do both trips in a 12 month span so that we could get APs and save on tickets (more money)
But then I had to buy more points...so a month after going into ROFR on contract #1, I had a second resale contract being sent to ROFR. (More money)
Then we bought a direct add-on of 25 points to get member benefits and discounted APs (more money)
Then I figured we should get the TIW card since we're going to have two large groups going (more money -- direct price of $150 -- but you might end up spending more to "save" more)
Then we had some orphaned points that were going to expire, so we booked an impromptu F&W trip, so that was two flights, food-money and earlier start date to AP passes (more money). It also used up some of the other points I hadn't planned on using since I could only get 1 BR units with such short notice for F&W, which meant I had to buy some transferred points to make up the difference for our second grandparent trip (more money).
After buying the APs, I figured we might as well sneak in a couple more trips, since the entry is free. I'm doing a solo trip and then I'll be taking my oldest DD by ourselves to celebrate her 5th birthday (more flight/food/points costs)
So it can be a slippery slope.
In my case, our initial contract was around $22000 -- which is what my wife thought we would be spending. Fast forward 18 months, and we have spent about $45000 for 305 points. We've spent $1650 on 3 APs -- I have no idea how much our food/alcohol purchases have been -- but in the three trips we've already taken, I would assume it is at least $2000-$3000. Those princess character meals are pricey. I've transferred in around $3000 worth of additional points to cover some other trips we have planned. Flights have averaged out to about $300 a person (4 of us -- so $1200 a trip). I also have stocked up on 7 day park hopper passes from parksavers.com when they had a really good deal, so I think I have about $6000 worth of park tickets just chilling in my
MDE. All in all, I have probably spent about $60-$65,000 on Disney related stuff -- and it all started out with the idea of saving about $2500 per trip on our hotel.
In short -- lodging is just one of the expenses of a Disney vacation. With DVC, you'll end up going more often, which leads to more points and travel related expenses.
