Garden Grocer is the best way to save money at Disney. If you want to spend 3-4 dollars every few hours just to stay hydrated at the parks ignore my words. Otherwise buy a 24 pack of water from Garden Grocer and put some snacks in your bag to avoid getting taken advantage of by Disney's overpriced snacks.
Brilliant service with several updates on our order, food was at our hotel upon arrival and was reasonably priced.
Just what I expected.
