Yes, water bottles are encouraged.No other food or drink, though. 😁
Yes, you can take it into the caves but they don't tell you that until you get to the entrance. There are water fountains close to the end of the tour.
Water is fine as long as you don't take any other food or drink.
You can take water in the caves as well.
You can bring it in your backpack
Yes. It's very humid in the caves.
Not into the caves but around the shopping areas and outdoors you can.
