My own resorts (3) are Desert Spring Villas and they also provide a lot of complimentary activities. So, if I exchange into Canyon Villas, I don't expect to have to pay for something free at my own resort(s). Or at least I don't expect to pay a whole lot.
But, it made me think. Say, 20 people show up for an activity. That is 20 out of perhaps 400 guests. Or 5% of the guests participate. So, if they are giving out free wine and you do the math: 20 people x 4 ounces = 80 ounces or perhaps four $10 bottles of wine. $40. Even if I'm off by 100%, it isn't a big issue. The cost of the Marriott labor is not insignificant. Assume 3 people x $20 an hour x 1 hour (for a wine social) or $60. So a single event may cost $100 or perhaps a bit more. So, suppose Marriott does this every day of the week. $700. Now with 400 guests, that equates to $2 per guest per week.
Looking at this from another perspective. Assume that there are 10 activities a day (some are pretty trivial like Bingo). Assume that there are 5 full time associates earning perhaps $20 an hour (I don't really know, but I suspect that Marriott doesn't pay a whole lot to many of these people). So that is $4000 a week. Divide that by 400 guest units and that is $10 a week per unit. Again, not a whole lot compared to the $1300 plus annual MF. Again, even if I'm off by 100%, it isn't a startelling amount.
Also, you need to look at more than the percent increase and look at the cost per owner. For example, if the cost of a 1st class stamp went up by 100%, some would gast. But that would (for me anyway) amount to maybe $10 a year. So percentage increases may be less important than total costs per owner.
What rubs me sideways is my resort (DSV) and your resort (Canyon Villas) both are paying for those activities. So are resorts like the Grand Chateau. But some resorts, like Newport Coast, charge $16 for three or four 2-ounce samples of beer (their cost? $2 supplies plus associate labor). They charge $20 for 4 tequila tastings. (their cost? 4 x 3/4 ounce = 3 ounces >> $3 supplies plus labor). So, even if I'm off by 100%, Newport Coast is actually trying to profit from these activities. I think that Marriott is amply rewarded by charging (IIRC?) about 15% of our MF as profit (in addition to covering all of their other costs). So they are making close to $200 per owner unit.
