We're a family of 5 with three little ones (4, 2, 6 months at time of trip) and I'm not excited about the idea of bringing 3 car seats or renting a car that would never be driven. Since uber car seat only guarantees 1 car seat (and has questionable amount of driver participation at this point) the only thing I can think of to get us from MCO to our universal hotel is the superstar shuttle. Is there any alternative I'm missing here that would be able to provide 3 car seats or not require any at all? Thanks.
