The point is this is a labor/cost move, and it's a slipperly slope. Maybe THIS particular change doesn't bother you, but the next one might..and there will be more. It's a slow decay of service. If people don't speak up, pretty soon we'll be staying in Motel 6 equivalents.
Nicely put nunzia!
Now, I admit I must be missing something. With all these posts in this thread about how this change has been made in response to the sanitation/hygiene of glassware issue in resort rooms, why are they starting this move to replace cups and glasses with disposables at the DVC studios?

This issue raised its ugly head at WDW at the Contemporary resort. In spite of suggestions that this change is resort wide, I have yet to see mention *anywhere* on the resort board here that plastic glasses and foam cups are now being stocked in the mods or deluxe resorts - and the question about whether there have been any changes in the traditional resorts has been asked.

Surely if this change was made in the non DVC resorts, *someone* would have said something by now.
I am also confused about this: What sanitation/hygiene issue are they resolving by replacing glasses and mugs with disposables in villas which are equipped with a sink in the kitchenette and supplied with dishwashing liquid?
It doesn't take much effort or time in the studio to fix any potential sanitation problem with real cups and mugs, however in the traditional resort rooms, that simply isn't the case. Again I ask, why did they implement this change in the studios at DVC resorts? I have to agree with nunzia - it is more likely because of cost savings.
Glasses and mugs do scratch, break, crack, get lost and stolen, and all this means there is a certain cost to maintain a sufficient inventory. Last time I checked, it was possible to purchase a very large quantity of foam cups or plastic glasses for the cost of a few ceramic mugs and glass glasses. With this change, Mousekeeping can now reduce the inventory they need to maintain. With all the cups and glasses that won't be need in the studios any more, they probably won't have to purchase any new inventory for quite some time!
It definitely costs less to provide sufficient quantities of disposables, not just in purchasing, but also in labour. Disposables take up much less space and are significantly lighter to move around than the real things. No need to replenish disposables on a daily basis either...they can (and should) provide a bunch when they set the studio up at the beginning of a stay, then (should) replenish on T&T day.
Here's an idea...for studios, maybe now it can be renamed TT&D (Trash, Towels & Disposables) day... Gee, wouldn't it be nice if when they replenished the cups and glasses, that they also replenish the cheap paper plates and bowls too...
OK, so that's not going to happen.
I am less than thrilled by the suggestion that DVC would have studio guests go to the restaurants (or anywhere) to replenish these items ourselves.
If self-serve is going to be the standard operating procedure for the studios, while they are at it, why not have studio guests pick up their own sheets, towels and toilet paper to set up their studio themselves? Wow! Maybe they could also have studio guests empty their own trash, then eliminate the T&T service too! Just imagine...the potential cost savings are quite staggering!! The studios could become the equivalent of the self serve section at a gas station, while the 1BR and larger will be the full service section.
OK, I've taken all this to an extreme...but to make a point. The ceramic cups and glass glasses were not specifically itemized in the POS or our contracts - and it seems they are going the way of the dodo bird. Without looking it up, I can't be certain - but I highly doubt things like toilet paper, pool towels, sheets, blankets, toasters, coffee makers, cups or glasses of any description are itemized there either. It simply does not strike me as acceptable that DVC members are going to have to supply basic items ourselves in order to enjoy our vacation if we opt to stay in a studio. DVC accommodations are *supposed to be* deluxe, and there should not be significant differences in quality between the various levels of villas within the same resort.
Apparently, the folks in charge of the nickels and dimes at DVC are sitting around and looking for things they can take away in order to maximize profits - this isn't the first change, and if things like this stick, like nunzia, I'm certain it won't be the last of the downgrades we'll see.
