"2 months of relentles convincing"
We stayed at SSR with friends on rented points for our annual Halloween trip to
MNSSHP this past October. This was our (mine and DH's) first time at a DVC property. I had never even heard of DVC, renting points or the DIS boards until recently and neither had he. Well, I decided to take the tour during our second day at SSR since everyone was napping one afternonn and I was wide awake, intrigued and wanted to learn about "the best kept secret". Needless to say, I got hooked on the idea then and there. I came back overjoyed with enthusiasm woke up DH and began to bombard him with all of the wonderful details
He hit the brakes and did his best to tune me out
Nice try...you'd think after 10 years he'd know there is no tuning out the loud Latin girl
I'll give him an A for effort though. He doesn't budge and we enjoy the rest of our vacation. Undaunted, I get back home and join the DIS boards immediately and begin lurking and learning. Armed with facts, figures, the possiblity of a smaller contract through the TTS and the voice of experience on these boards (don't wait, buy sooner and more points) I plead my case again
He considers everything I've said and tells me, "Well maybe in a few years, but not anytime soon."
AHA!!!! I see a chink in the armor, we've gone from "No" to "not yet" this is going better than I hoped but I need a new strategy
Over the course of the next month I bring up smaller contracts I find on the TTS site and how much $$$ we'd be saving in the long run etc. and so forth. We wind up back at WDW for Thanksgiving and stay at Pop Century. There were several snafus in terms of service
and suffice it to say that the feeling was different than when we stayed at SSR. Naturally, I point this out at every opportunity and proclaim that I am never staying at another value resort again
After our trip I continue right were I left off about how awesome it would be to join DVC
Finally, a couple of days before Christmas he decides to consider one of the smaller contracts available. YAY! he's figured out I am not giving up on this
Later that same day I discover perusing through the boards the referral promotion. DH has a co-worker that owns at OKW. Once I told him about that promotion he went for it
I called my tour guide before he could change his mind! She suggested I start with 160 points. I explained that I was surprised to even be making that phone call at all so I wasn't going to push the issue
Before you know it DH calls up and says it would probably be a good idea to get 180 points to start
Stunned, I call back the tour guide and explain that I've no idea where my DH might be locked up but they can keep him since I really like this other guy that wants us to have more points
We signed on Christmas day and I am so happy
I am thrilled to be a new DVC member, thrilled to have a very cool DH
and thrilled about our upcoming MNSSHP later this year!
What is not re-counted in here is how many different ways and spreadsheets I found to show him the numbers! I initially did it by hand on the way back from the MNSSHP trip. Then later I found several different versions of number crunching performed by DISers over the years. I brought him all of them.
6 months later we bought another 150 and just payed those off last year.
