We're headed for vacation in a couple of weeks. Obviously, seat belts are required for everyone. Taxis are exempt in Portugal and we likely will not drive often, but do have use of a very (very) small two door car.

Any suggestions for a travel-worthy (light and small) car seat for travel? At a loss. He's not heavy enough for the Britax Laptop, which may or may not even be legal.

Suggestions?
