last year I came across a Dollar code that saved me almost $500.....every thing was running $500 per week for a minivan...so instead of paying over $1100 for 2 weeks I ended up paying $600 with dollar...
So, start looking now and keep searching....I would book as soon as you find something ok..you can always cancel it later if you get a better deal...I also, found that in about oct...it was more and more difficult to find a company that had available cars...
