We've had a Seasonal AP in the past and yes, as long as you are not in a blackout period, you're fine! We forgot about the blackout period for concerts at USF and that year we were at HRH over Thanksgiving, so we could not get in to USF on that date. Quick and easy trip to the hotel front desk and just the price difference of an upgrade paid and we were ready to go! So - for us it was worth it to convert our original tickets to Seasonal AP's, then pay the price difference later if needed to move up to the next level if we found ourselves going during a blackout period. Doing that again next week. Oh and yes do use that link to check APH rates for the hotels!! Feel free to message me if you have questions on this!
