I'd love to know the policy about bartenders filling Tervis or Bubba Keg like cups too. Last time we were at CN when I checked the boards it seemed like a "no-no" to have the bartenders fill your own cup, maybe you could bring a Tervis and fill it with the drinks the resort provides in their own cups? We just bought a can size coozie when we were there that we put on the drink cups provided and it worked beautifully to keep my drink cold and not "sweat" all over the place. That same coozie is now 1st on my packing list for the 3rd year now
I have read that bartenders are not allowed to fill your mugs but that you can pour your drink into them after being made. We have 24oz thermal cups with screw on lids that I use when on vacation. Not tervis (Walmart) but they work great and I plan on bringing them. Couples should consider selling something similar with their logo on it in the gift shop that you can have filled at the bars.
