Just a comment about calling your guide. I am in sales (Software, not Timeshares) however, I still feel qualified to respond. Remember, your guide has a monthly sales quota that they must hit in order to be in good standing with management. They are there as a last resort if you have a complaint with DVC, and have exhausted the "Chain of command" so to speak at member services. They should not be called for issues that member services normally helps you with. Tickets, reservations, etc. are part of Member Services.
I am assuming that you are a (Fairly) new member, so I understand the confusion about who to call. The people at Member Services are really great and can help you with anything except adding on additional points. In fact for an issue like this one, Member Services probably know more about the new pricing than your guide would.
