Thanks for the info.
How many people were in your party last time? And do you remember if they limit your luggages?
From their blog they said that the $72 sedan is for 3 people to sit comfortably plus 2 check ins and 2 carryons. More than that they want you to move up to their SUV which is $113.
2 last time and 3 the time before. With the 3 people we each had 2 rather large check in bags along with carry on bags and had no issues. Oldest adult daughter is only 5'1" and we are all average to slim so none of us take up more than average space so I don't recall feeling cramped in the least.

I can't imagine just winging it with transfers!!! What are your thoughts?
