DH, Me, DS1yr, DS3yr & DS4yr are travelling to orlando in a few weeks, and we are taking our own car seats for use in our hire car, with all 3 kids needing car seats it was going to cost $500 extra on the holiday to hire them for our duration. DS4yr will have a booster which fits in our suitcase, but the younger 2 have proper solid car seats. I know we are allowed at least 1, but has anyone checked 2 into the holds without paying an extra cost? I have checked virgin website and their customer services too already.
I'm sure you'll be fine. Make sure your bags aren't overweight though as they made the people at the check in next to us re-pack at the check in and also they weighed our hand luggage and DS's bag was very heavy as he had lots of books in it (revising for exams) so they made him take some out and DD had to carry then.
