The MFs are all set out in the budget statement, that's the "Why". I'm sure abuse goes on at all brands and owners pay for that too.
I haven't seen an analysis that says MVC have the highest MF with no midweek clean, can you provide the info on that?
I can only compare to what I own.
HGVC is on average $300 - $1000+ cheaper MF-wise and includes tidies and sometimes full cleanup - no questions asked. We've traded into Four Seasons Algarve (not same as hotel chain), and they had mid-week. Fiesta Americana in MX has midweeks and even cleaned the dishes.
For resorts, we pay $850 (1 bdrm) and $1150 (2 bdrm) on our 3 HGVC club units per year. We get mid-week and sometimes full mid-week clean for all. Tip housekeeping and they will do it more often.
To compare: I can buy 3(!) more HGVC 2bdrm resales units to pay the same MF as we pay for WKORVN MF. We have traded those points into Hawaii, Cabo, Europe, skiing and Hiltons via points. Our WKORVN (enrolled in Abound) and WKV approx $3500+ per week and $1500+/week respectively! (At least we get a midweek tidy.)
We also own a deeded HGVC week in expensive NYC and pay approx. $1750/year in MF - and that's our most expensive HGVC unit - it includes lounge access with breakfast and evening heavy appetizers/alcohol included in that price for my entire party daily plus tidies. I can add nights or extra rooms for < $100/night to accommodate family and they get lounge access too.
Evening appetizers are not airport lounge Chex fare, it changes but frequently includes salads, sushi, vegetables, shrimp, cheeses, guac beer and wine - it often substitutes for light dinner for many owners.
How much do you pay in Abound for a week in NYC? And what amenities do you get?
To be fair: HGVC doesn't offer as many activities as MVC resorts. Some properties offer no activities, but we do not use those so if MVC eliminated or charged a fee to keep MF lower, I would be in favor. Locations amenities can vary between HGVC and MVC. WKORVN is superior location IMO to HGVC Maui but HGVC is less crowded and has nicer pools. HGVC has superior/equivalent resorts on other Islands and Cabo.
MF this year and last two years only went up single digit - 5% or less in most cases (MVC's excuse for double digit? - inflation
)
