I tried to get rates from national alot of times over the last few months. Both with Emerald Isle, and the entertainment coupons. I eneded up making ressies for a mini van for 9 days through Dollar for 347.20 with all taxes, using a code that I got from these boards, and the many helpful people. I am going from the end of march until the first week in april. This was the same price I was going to pay for a premium car through National.
Just a thought....how many folks do you need to get into the van...right now you can rent two medium size cars for less than a van and have two options for the group...we did this last year with 4 adults and 3 kids and was by far the best deal both for $ and also allowed us to get away from each other once in a while for a breather...ted....and BEWARE of ALAMO....many many bad experiences on these posts and I am one of them..never again..I will always rent from inairport dealer...good luck
