DH and I are taking DS (11 months) to Aruba next month. I have some questions for those of you who have traveled with young kids.

1. Do I need to buy him a life preserver? He will only be in the water with DH or myself obviously so I'm not sure if this is necessary?

2. He will be a lap baby on the plane, but once we get to the island, if we were going in a cab or something I'd want him in a car seat. But then I'm thinking, if we put the car seat in a cab to a restaurant, we'd have to take it out and bring it into the restaurant and then put it in another cab home. Is this what is typically done?
