The hockey ticket prices all vary depending on who they are playing, I am looking at doing a Washington Capitals game at our Thanksgiving if they are playing at home and I think the schedule is due out around June 10th - ish!
As for the drive, again depending on weather you are looking at a good 22 hours drive, we did it in 2 days and with breaks it was 12 hours in the car day 1 and 14 hours day 2. Lots of options for staying in Tampa and I guess if you are staying Christmas Day you might find it pricey.
Lots of options and choices, happy planning
