Well CS Mexico is covered but outside. America is 100% inside. There is small seating inside Japan but most are outside but shady. Norway is covered and sort of inside as walls behind and in front. Just sides are opened.
AK is just pizza place and we ate this last week. Was not good but was short line and guess that is about only positive I could say.
I would not add TS just for staying indoors though. We were there last week (first week Jan) and weather was fine and eating outside was no problem. Plus with the ones listed, you can be flexible and move to a country with cover or indoor seating.
We liked TS but found HAVING to have reservations for anything, offset the flexibility of the CS options
