There are lots of ways to save money.
I have a Disney Box that I start putting items in as soon as we get back, all the stuff you must have for the trip, We shop at Sam's club alot when they have a small size included with shampoo or body wash. I put it in the Disney box so that when we get ready to go I have all that stuff ready and don't have to fork out extra money for it. I also shop all along starting about 2 months out.
We take a cooler to keep everything cold and add ice and drinks as needed. I also take a collapsible cooler for the pool.
We always take a case of water, soda,& gatoraid. Which save alot of $$$
We have breakfast in the room, or lunch by the pool or when we get back from the parks late. We like to have deli meat and cheese, crackers, dip, cookies, chips, Banana's. I just get the simple stuff.( family favorites)
We never get the mugs, If it comes with the package we use it as a souvenir.
We have split meals before, Dh and I and DD and I.
We buy souvenirs the last day so we really get what we want. When DD was little I would buy at a
Disney store on Clearance.
