When we rented a mid-size in June there were at least 2 chevy HHR on the mid-size aisle but we also noticed that there was one on the full-size aisle so I don't know which category it is supposed to be in. It was the second time I have rented a mid-size and have seen the HHR so hopefully it is there when you are there. We have also gotten the Mazda 5 hatchback which was very roomy and plenty of space for luggage. It actually had optional seating for 7 but then there wouldn't have been much room for luggage.
We get a "full size"--last time it was a Sonata w/satellite radio! Couldn't have been more pleased.
Are you asking about full size or intermediate? Lots of folks here are telling you what they got as full-sized.
About a year ago Alamo downsized its fleet designations. In the past year I've twice ended up with what was really a compact car when renting an "intermediate". I talked about it in this thread from last November, and my observation three weeks ago wasn't any different: http://www.disboards.com/showthread.php?t=2324364
These days I stick to renting "full-size" cars if the family is with me. I can't easily get kids, carseats and stroller plus luggage into a compact. (The last two "full-size" cars I've gotten have been Altimas; legally a mid-size car.)
I reserved a midsize through Alamo at MCO for our July trip. I thought I've done it before and was able to rent a Chevy HHR? Does anyone know if the HHR is considered a midsize or if they even have them still?
Anything in the fullsize row is designated a fullsize, however sometimes they put fullsize in the midsize or intermediate rows. I have never seen a compact in the midsize row. Sometimes they put intermediate in the compact row. Why someone would choose a compcat from the midsize row is beyond me. We have had the hhr 3 times now, and always been happy. 3 adults in the back seat would be a stretch, but 2 adults in the back and a child fit well.
