12. Buy Groceries
This may seem unconventional, but purchasing groceries for your trip can actually save you money. Many guests have luck with services like Garden Grocer and Amazon Prime Now. If you place your order ahead of your trip, everything will be delivered directly to your room upon arrival. Purchasing a water bottle or a small snack at the parks can be pricey. Ordering a few snacks and cases of water for your trip is economical and convenient.
