Serious question because these comments also were constant back in the previous 2008/9 gas price spike...
Do you all really see the gas prices as the edge of the cliff for going on vacation? Our longest trip was Disney at 1100 miles. At our lowest in decades of around $2.29 just to make the math simpler, compared to currently $4.29 for my area, that increase would give a $68 one way difference to the trip.
We spent $2200 on the booking which is extremely cheap compared to what you spend now, had food costs budgeted, a hotel stay for the trip down and had a hotel in reserve for the ride back (we ended up driving straight through). Is $130ish enough to cancel when it's not much of a percentage of the over all trip when you're spending so much?
Obviously give or take depending on the mileage your vehicle gets (my numbers is 32 mpg), but if you're driving around daily at 18-20 mpg after you've managed through the 2008/9 and complaining about gas now, I don't have any sympathy for you (talking to you, huge SUV and/or massive truck owners who are being the most vocal at whining and crying) but most drive something that should be getting close or better than 30 on a long highway trip.
