Spring Training Tickets

Taking my wife and my parents for a week in March to Spring Training. Flights, rental cars, hotel all booked. How hard is it to get tickets? I'm looking at ticketmaster, vivid, seatgeek....no official seats yet on MLB.com.

Am I going to have a difficult time getting them? How much can I expect to pay? I was thinking it wouldn't be that difficult, but now I'm a little worried. I used to work for the Cardinals and Rays in St. Pete and I don't think back in the early 2000s it was that tough to get a ticket, but maybe becuz I worked there, I just don't remember right.

Any advice would be greatly appreciated.
