I have read through the sticky thread with the options, but did not really find an answer. I am not really wanting to do the Mears Shuttle because I do not want to be locked down to a reservation time. So I am thinking a taxi would be right for our family of 5. However, my youngest is a small 5 year old (size of a 3 year old), down there he does not need a car seat but we use a booster for him in WI. Do taxi's have booster seats in them? Any other options people have used with a child needing a booster seat?
