We are planning a day trip to Legoland the day before our cruise in November of this year. We will be renting a car from MCO in the morning and returning it later that evening. How do I go about getting the cheapest price possible? I've never rented a car before and am pretty clueless. Also, our boys will be 7-years-old at the time. Here in PA they are still required to be in a booster seat. How does that work with booster seats in FL? We weren't planning on bringing our booster seats along as we will be using Disney transportation for the rest of our vacation and don't want the hassle of storing the booser seats in our teeny, tiny room on the ship. Can I rent boosters?
