OK, ready, aim, fire (at me): I have no problem with the idea of walking a reservation (and I've done so exactly once...at 11 months, to get Thanksgiving week 2009 at BCV)...I don't have a problem w/people using the rules as the rules are. It's a different issue if we're talking about what the rules "should" be...but using the rules as the rules are isn't, in my mind, cheating or immoral or in any way wrong.
OK...you-all can hate me (or not)...
Having said that, I'm not sure walking a reservation is really necessary...I did walk my 9-day BCV T-giving trip...and found out 2 months later when I called for another reason that villas were still available (at 9 months out) for all my dates, in a studio, at BCV...
Not sure if that would be true for Christmas week/New Year's Eve...but to find out that there were still villas available at 9 months out on the Wed before T-giving and T-giving itself at BCV suprised me a LOT...I won't be "walking" T-giving of 2010 (we go every T-giving), but I don't feel guilty about having done it for 2009...I "needed" those dates and that resort (and a studio)...I had no flexibility for that trip (for a variety of reasons)...for me, the "guarantee" was necessary as I didn't have an acceptable fall-back...
Yes, it works. As noted, not sure it gives anyone any real advantage...but it's legal and not all that hard to ... it takes multiple phone calls, but if you have the time to make the calls, it's an easy thing to do...
One thought, though: if you walk starting with Fridays and Saturdays, and aren't going to use those Fridays & Saturdays at the back end, you're tying up points...that could be an issue, depending on how many points you have and how you plan to use them...but that's "bookkeeping" ... if you have the points, you can walk; it works and it's legal...it may not be "necessary," but if it isn't, then no harm is done if you do it!
Happy planning...
