Spring training practice schedule for night games?

I'll be checking out spring training later this week, and going to one of the night games. I was wondering about the practice schedule on the fields. Do they maintain the same 9:30 am practice time for the big league players? or do they adjust for the later game time. I'd like to be able to see the players up close and maybe get an autograph or picture. but wasn't sure if I should plan on two trips out one for the morning practice, and then the game, or just go out a a couple of hours early before the game.

TIA
