It sounds like you are committed to several years of visiting WDW.
DVC ownership is a nice way to have more room and luxury amenities. As Missy pointed out, you give up some of the deluxe accommodation niceties, such as daily housekeeping (meaning no daily fresh towels and the bed doesn't get made, unless you do it).
Resale is obviously the most cost effective way of getting into DVC. You can do small add-ons direct after you join, if you desire. Currently, you can add-on as little at 25 points. Keep in mind that they are still actively selling AKV, and with the Grand Floridian Villas soon to be on the market, they may be actively selling AKV for a long time. The current direct cost for AKV is $145, so a 25 point add-on is going to be over $3600. You would be better off saving up and buying a larger contract to begin with if you anticipate wanting more. Plus, the larger contracts can be had for less, and the closing costs are about the same as for the smaller contracts. AKV is fairly easy to get into most of the year, unless you want value or concierge.
Some other important principles of shopping:
- if you don't ever see yourself being able to book in the 7-11 month window, home resort doesn't matter -- buy the best value (SSR).
- make sure you understand the limitations of the Use Year and try to buy something that will work for your travel patterns the majority of the time.
- if you want to stay at an Epcot resort for F&W or the early part of December, you must own there.
- if you want a value or concierge room at AKV, you usually need to own there.
- contract of less than 100 points seem to sell in less than 3 days, and I am guessing that they go for asking price (which is particularly true for BWV and BCV). If you want a small contract, you need to call as soon as you see it listed and you should probably offer asking price, or someone else is going to get it. TTS just sold a loaded 100 pt AKV contract today for $65/pt. It was listed today and gone by 1PM. I know, because I was the third person after the new owner to call about it!
- keep your eye out for "loaded" contracts -- those are the most valuable, but make sure the points will be in your account in time for banking, if necessary.
- choose a home resort that you would be happy staying at if nothing else is available, or if DVC changes the rules. There is nothing worse that paying all of that money and then being stuck at a resort that you don't want to be at.
When you say "Lodge", I assume that you are talking about Jambo House. Don't write off Kidani. There are many really nice things about Kidani, and we personally like it better than Jambo. We love our AKV home and would be completely satisfied if it was the only place that we were able to stay for the next 44 years of Disney trips.
Keep reading and learning. You came to the right place!! Good luck with your decision!
