Cross-stitchma,
I also vote for Britax. My son has 2 Britax Roundabout and 1 Britax Advantage (we put 1 in each car and 1 for spare to save time for strapping it to the car each time). My daughter who is 8 months old is using Graco Snugride (my son used it before). We have no doubt to Britax, safe and comfortable. Graco is good but infant carseat always have a problem when you put it rear-facing - it would move sideway, I put a towel underneath the carseat and it won't move about then.
One thing to reminder you - when you land, remember to ask the person who is going to pick you up to bring along a carseat. You son is 9 months old, he needs an infant carseat rear-facing. If you are planning to take Shuttle bus, you have to bring along your own carseat. Otherwise, any shuttle bus or taxi will refuse to take you. It's by law that infants and kids under certain height and weight have to be in carseat for safety issue.
