Sorry I don't have recommendations for hotels but I can tell you that there will be plenty of Packers fans staying at the Hilton Clearwater Beach - the Packers tour company has packages from GB and Milwaukee to the game and the Hilton is their lodging destination.
Also, there are two Pep Rally's being held on the 20th hosted by PackersEverywhere.
"The festivities will take place at two different locations in the Tampa Bay area Saturday. The main pep rally will be held from 6:30 to 7:30 p.m. EST at Ferg's Sports Bar & Grill, located at 1320 Central Ave., St. Petersburg, Fla. The second event will be held from 8:15 to 9:00 p.m. at The Varsity Club, located at 24091 US Hwy 19 N., Clearwater, Fla."
I found this board while trying to find a reasonable way of getting to the game from Largo/Clearwater via anything other than driving but so far buses/shuttles don't seem to exist. There is something called BowlBus on-line that
may run a bus but it's not confirmed yet and it's $45 per person.
Fellow Ontarian and Packer fan attending the game.
Go Packers!
