With all the changes going on at Disney Hollywood Studios(DHS) I’m looking forward to my next visit. As for saving money its same across the board with all Disney properties.
Plan ahead so you get to experience the attractions that are on the top of your list, and or eating options.
We always do the same as with all the parks try to plan a late lunch and bring snacks with us into the park. This sticks with the principle that time is money. For every meal that you sit down for its somewhere between 1-1/2 of time and if you factor in the cost it can turn out to be significant. Also with your own snacks while waiting for a show or an attraction you can eat it.
This is important because next to Animal Kingdom this has the shortest hours of operation.
With the expansion coming in the next year or two it will be interesting to see how much longer they keep this park opened.
