We are flying, but I plan on ordering juice boxes, Horizon milk & water and having it delivered and then I'll pack stuff like fruit snacks, granola bars and some stuff for the baby in our suitcase, so we might save there. And then buy things like milk to keep in the fridge...
I just adjusted a spreadsheet I was working on earlier last month with the different prices (so it just depends on if those prices changes are permanent), just included the 5 most important TS meals and included the CS locations I think we'd eat at + what we'd more than likely order (no desserts and an occasional soda plus considered what we could share) & allowed for 3 refillable mugs & $12 in snacks a day. It came out $30 cheaper. So I guess now I need to decide if a $30 savings is worth it for me, right? LOL
As long as you are ordering a grocery delivery.... Get a case or 2 of soda. That will be a lot cheaper than 3 mugs. And then you have it cold and ready in your room, instead of having to walk across the resort for a refill.
You can get a case of canned soda for $6. I believe you are staying 5 nights?
So you can get 2 cases of soda --- 24 cans of soda, enough for 5 cans per night, for $12.
Or, you can pay $45 for the mugs.
For the mugs to equate to ordering cases of soda -- You would need 8 cases of soda. Each mug refill is about half of a can. In other words, your family would have to drink about 30-40 refills of soda per day, in order to get fair value.

NO YOU CAN'T HAVE POPCORN!! This is why we love the
