'2-week' calling
to be honest, calling two weeks ahead may be about 50 weeks too late......owners usually place requests at booking a year ahead, and naturally they get top priority.
.....and depending on the % of owners occupying, it sometimes doesn't leave many units available for traders, period, upgrade or not. You apparently did far better than the total number of first-floor occupiers, so maybe you did get the very best upgrade.
The BEST predictor of possible upgrades is the percentage of owner occupancy at the resort, and it has NOTHING to do with what you traded.....obtaining the trade week initially does have something to do with that, but less influence from what you traded.
I'll bet there were many OWNERS occupying there who also had second floor units. Count the number of first-floor units in the entire resort, and you may not have done so bad.
Experience will best show you how things work, but don't expect a last-minute request to do much 98 % of the time. It works only sometimes...i.e.,when it CAN be done...mostly, it can't.........the system works just like it should. I think your disappointment this time falls under the category of unrealistic expectations. Next time you may be pleasantly surprised. Things tend to balance out "in the world of trading". jme
