I usually book off the aisle with National since we are only a party of 4. But friends are flying down in April (2A, 4C) and they need a minivan. I booked them a minivan (Chevy Uplander or similar) and got a really decent rate (they were booked w/ Enterprise and would have had to go offsite on the shuttle, but w/ National they are paying $7 more but are onsite). However, National offers both a 7 passenger and an 8 passenger option for minivans. So my question is...when she gets there, she will go out to the garage and head for the "minivan" aisle. Can she take anything that is on the line in that aisle, whether it's an Uplander or a Sienna (the 8 passenger option)? Just want her to be prepared. She's an Emerald Club member so she can bypass the counter and go straight up. Thanks.
