We are in the early stages of planning our trip to St. Lucia. We'll be bringing our 2 year old son along. Leaving his big, bulky car seat at home would be ideal. Do rental car companies on St. Lucia also rent car seats? If so, are they generally clean and how much extra is charged for them? Also, does anyone have any suggestions for the best car rental places that would have car seats? My concern is that I would reserve something and then get there and they don't have one. Thank you.
