We leave for WDW one month from today - we are so excited! I know it will be very warm while we are there, and am wondering the best approach for water. Is it better to send it ahead of time along with snacks that we order from either Amazon or Walmart, just get counter service ice water which I hear is free, or bring some sort of water bottle with a filter for the ice water? If the ice water is good enough, then I don’t want to have to bother with having water sent. Any thoughts or advice would be appreciated!
