Cath is right. I too am looking into this as well. Last trip we used the Alamo seat. Never again it was in very bad condition and cost is so high. I sent an email to the county sheriff's dept and this is the reply.
I am responding to your email regarding child passenger safety during your
trip to Florida. Thank you for taking the time to ask about what is require
to keep your child safe while on vacation here.
Your question was:
Our child will be 3 years old. Do we need a full child seat or is a booster
seat all we need ?
It is a requirement under Florida Statute 316.613 that your child be
PROPERLY secured in a child restraint device that meets Federal Motor
Vehicle Standard 213 (see fine print on the side of your car seat that would
state that it meets this criteria). If your child is over 40 pounds, a full
back or backless booster will be an appropriate choice. The term "proper" in
our law requires you to use the car seat as directed by the respective car
seat manufacturer.
I think it is a wise thought to bring your own car seat, as long as it meets
the previously mentioned requirement. If it is a Britax, it should meet both
European and US safety standards.
I hope this was helpful. I will be out of the office until July 15th, but if
you have any further questions please feel free to contact me
and I will assist you with any other questions.

We will be taking our own car set. Will use on the way to the airport, take it out and place in a black plastic bag and label it and place in the cargo hold, job done..
A little hassle but worth it to be sure your most valuable item is safe.....
