I’ve found that for most resorts, they are great at dealing with “minor” needs like more plates, more towels, rooms not being clean at check in, etc. Where they struggle is on rarer requests like your fridge not cooling sufficiently. I had the same issue at VGF and I almost had to put on my warpaint to get it resolved. I’m not sure if there is just no solid procedure because it doesn’t happen often enough or if there is a shortage of fridges, or what the issue is, but oddball issues really seem to frazzle the front desk and housekeeping. Same thing with bell services- they are great when everything is normal, but one hiccup and you have basically exposed the rotten underbelly underneath. They put a delivery bag marked refrigerated on a shelf and it spoiled, and after 3 days of promises of replacement by no less than two different managers and it never resolved until I got home.
They are very good at fixing minor run of the mill issues, but if you have a real issue you are gonna see some unpleasantness. Riviera still has the best service of any of the dozen or so resorts I’ve stayed at the past few years. They must have a good GM.
