I definitely would have made some changes had i not booked things so far in advance (DVC points rental) and didn't have a large group going with us. That said, one day I will be dead and I can't take my money so I'll keep building memories for myself and my family. I went back in the late 90's early 2000's when it was around 65-68 cents and it sucked then too. I much preferred my last trip when it was at par. Not sure going forward how often I will head down but that is because everything in general is more expensive. 70% of what we consume is imported including Gas since we have few oil refineries. Oil drops, Dollar drops, Gas prices go up. In turn food goes up, clothes go up, vacation prices go up, home heating goes up, taxes and government debt goes up.
But we need to enjoy life while we can so while things will change for the majority of us, I'm sure we will still be able to find ways to enjoy life and the House of Mouse.
