My mom flew in/out of Sanford this past christmas to join us at WDW. I drove to pick her up and take her back. If you decide to rent drive some things to think about, it is about an hours drive and about $20 in tolls - I think round trip??? If you have little ones a driver might be better due to the need for car seats. One of the sites - Mears? - has an online quote form to figure it out, I think it was around $120. I also remember the check in line for Allegiant was long when I took my mom, but they have alot of flights that leave around the same time and they came out when it was getting close to see in anyone was still in line for flights getting ready to leave. Hope that helps
