We went last March and went to 4 spring training games in four cities (Lakeland, Kissimmiee, Dunedin, and Orlando (Walt Disney World of Sports). Had a great time at the first three, but about 10 minutes before gametime at WDWoS, it started raining heavily and eventually the game was cancelled. Hope to go back again as it is a really neat stadium. Purchased the WDWoS tickets from Ticketmaster and we received a refund except for postage due to the rainout.
We tried to get Yankee tickets, but didn't get onto the website until about 10:30 the first day of sale and they were sold out. Don't know what time they sold out. Anyway, I saw some on the website for sale, but they were very expensive. Approximately $150 each, if I remember correctly. Don't know if you would want to take a chance and try to pick up some from scalpers outside the stadium. They may be cheaper.
We also want to see some games close to Vero Beach and travel to and from there.
