In a short time I will be traveling to Tampa, and then to ST. Petersburg Fl. For the return though my friend and I are going to use the Amtrak bus, shuttle I was told is similar to the service provided for people going to Las Vegas Neveda which I have used before. Has anyone used this service from St. Petersburg to Tampa and is it only Amtrak passengers on it? Also is it a van or larger vehicle that Amtrak uses? Also my friend is going from Tampa to Kissimmee so she will be with me in my bedroom on the return trip. She has her own reservation number for that but can we get her tickets ahead of time at Tampa when we get off the train instead of waiting for that day?
