If you fly out, fly out on that Thursday since it will be cheaper. I checked on flights yesterday at expedia for my honeymoon, and flights seemed to have gone up. Plus you might need to rent a car too. Then again with gas averaging around $3.30 a gallon, I think it's a damned if you do, damned if you don't situation.
Personally, I think road trippin' would be more fun. Cram as many people as you can and take turns paying for gas.
I ended up getting REALLY cheap flights. But I'm heading to OH via LA (NY to LA....seeing Camp Freddy...then flying to Ohio) And all that I got for $409 with tax and all the other fees.
A rental car in OH is costing me $13.50 a day (through AAA) and the room I think is $89 a night or something.
Don't matter, I would have paid anything and eaten paper for the rest of my life
