One of the important and unique (at least to me) features of DVC is the flexibility offered by the opportunity to reserve at other DVC resorts at 7 months. I do realize that EVERY reservation is always based on availability (and that statement is very prominently displayed in all of our documents and in most of the presale literature).
I personally have always been able to get a non-home reservation within 7 months - sometimes multiple calls to MS were necessary, sometimes the waitlist was necessary (and that has always worked for me) - but I have never been disappointed trying to make a reservation within 7 months.
I always find it amazing that guides are criticized for touting this important (again, IMO) aspect of the DVC program.
A number of years ago, on this board, there were some quite vocal about guides mentioning this - even to the point of stating it was a lie. At that time I challenged those posters to give me a date when I would be unable to make a reservation within 7 months. No one even offered a suggested date to test the challenge. I'll stand by that challenge today and also sugest that as long as anyone is able to get a reservation within 7 months, the statement made by the guides is absolutely correct.
I would be very disappointed if the DVC guides failed to mention, as a selling point, the flexibility of DVC and the opportunity at 7 months to make non-home reservations. I would be very disappointed in any prospective purchaser who fails to read the documents before buying and who later states he didn't know/realize that all reservations are based on availability (IMO, the guides should not need to make a disclaimer stating that when it is so prominently placed in the DVC sales literature.)
