One thing to keep in mind if you have to drive in to the show, and plan to hang out at the Hilton (a MUST) - the parking deck across from Ocean Center is $8 a day (if you don't leave). If you have to leave the parking deck and then come back, the clock starts over, so parking can add up.
If you get down on Friday, mid-day, let's say - you can stop by the office of the parking deck and last year they were offering all day passes for the show (and I missed out). The office is on the lower level of the parking deck.
Because we took our dog, we did leave the deck several times to walk her, or go back to the room to drop off animals, take a shower before dinner, etc.
