BTW, Another option to save money can take some more research and effort but can really pay off: My wife and I both got BarclayCard Arrival MasterCards earlier this year. When you spend $3k in 3 months on each they give you 50,000 bonus rewards points that can be used for travel reimbursements.
If you use them to their best advantage, you can get at least $600 worth of travel credits out of those points on each card.
It turns out that ticket sales through the Undercover Tourist code as “travel”, so you can use the credits on those. We did so and saved $1,200 together on our park tickets.
