We need a minivan from 9/17-9/24. The cheapest I've found with an on airport rental car company was with National at $257.60 using the WWEB product code, and either priceless or ent contract code with the ent coupon code. We'd prefer onsite rental car company because we have a 3 and 5 year old and will need to bring car seats for both. It would be a hassle to lug car seats all the way to an offsite dealer. So, its either bring them and use onsite or don't bring them and pay the extra $100 + fees I've been seeing for car seats. The onsite companies I've seen are alamo, avis, budget, dollar, national, & L&M. Anyone know how I can get this 7 day rental any cheaper?
