Hi there,
All those years ago my wife got the jitters about spending all that money when at the DVC tour and I then had to get her drunk when we returned home, honestly, for her to agree to buy after we had returned. Simply call them at DVC, they will guide you through the process, it's painless. What happens, is legal documents and also financial papers are raised in Florida with your names for that level of ownership, they are simple and easily read. Once you are happy signed in the easily marked places then a courier company will come and deliver the documents to DVC, they used to use FedEx and that was great because you could trace the package all the way back to the States. It takes a few days later before you can book, although your guide will help again. Later on you will get a copy of the documents after the have gone through the notary and been lodged with the court.
Then it's easy vacations for the rest of your natural.
PS, My wife recovered from the hang over and never regretted it, although the price per point had gone up $5 and the exchange rate then was $1.4 to the £.
