It depends on where you're at and how seriously they take their kitchens. And how seriously you take your kitchen, for that matter.
In our TS system, the kitchens for the 2 & 3BRs are usually pretty well-supplied by TS standards, but they may or may not have a glass 9x13" pan (if they don't, they'll have a glass 9x9"). A covered bowl or two for the microwave. They'll have a set of pots like you'll find in a department store - fry pan, 1 or 2 sauce pans, 6-qt stock pot, that kind of stuff. Cookie sheets or jelly roll pans, but not both, and they're often in the oven so need to be pulled out if you bake.
Don't expect anything to be teflon, unless someone has bought a teflon fry pan and left it there. Don't expect pie plates, muffin tins or anything like that, although I've seen lots of the more specialized stuff here or there.
The condos we've been in supply TP, paper towels, some DW detergent, a little bottle of dishwashing soap, and enough laundry detergent for one load. They'll have linens - bathroom and kitchen towels, extra bedding for the sleeper sofas, etc. If someone staying there bought some and left it behind, they'll have aluminum foil or plastic wrap or any number of non-standard items.
In our system there's usually a grater, measuring cups, a teapot, an electric can opener, a coffee-maker, a blender and a mixer with three bowls. The bowls may or may not have lids. Spoons and pancake flippers and barbecue stuff should be supplied, however the scrapers are usually the hard kind so I bring along a rubber one myself. Measuring spoons seem more likely to be missing than measuring cups, so if those matter I'd bring some along.
We drive, so I usually bring along at least one 9x13" pan and a big stock pot. My family of seven includes 2 teenage boys - and one teenage girl who outeats both of them

- so I want to be sure to have the larger pot and can generally make use of two 9x13" pans if I have them. But I suspect I do a lot more cooking on vacation than most people - I love the opportunity to cook or bake without having to run some kid off to some class or meeting right in the middle of things!
If we were flying I wouldn't bring the metalware but I'd still bring along some repackaged herbs and spices - some people use those 7-day pill thingies for their spices, tucking them into a ziploc bag in the corner of a suitcase in case the compartments pop. If you cook mostly canned stuff or mixes, you don't even need those.
