I was wondering how easy it is to go between terminals. I have a stopover in vegas and will be changing airlines (from Hawaiian to SW) on my way to San Fran. I know that Hawaiian is in terminal 3 and I think SW is in terminal 1, after I pick up my suitcases does anyone know how I can get back to terminal 1 to check in at SW with my bags? I know that I could probably take the rent a car shuttle but I was wondering if there were any other shuttles that travel between terminals? It looks like you can only take the train after you go through security so I wanted to know if there were any other (free) way to go between terminals prior to checking in. Also, has anyone had any experience with the airport lockers? How much? How long? I will be back in vegas after 3 days in San Fran and I would like to store my bowling bag (tournament in vegas after that) somewhere so I don't have to lug it to San Fran. I may just take the bus and leave my bowling bag at MB or someplace close for a few days. Thanks!
