Upgrading Legoland tickets

[HHMcG]

We have two days planned at LegoLand late this summer. I plan to buy tickets using the BOGO deal in Lego mags or the Florida PTA deal. Only 1-day tickets are available through both of these deals. Can anyone confirm for me that I can upgrade my 1 day ticket to a 2 day ticket? I assume I can but was hoping for a solid confirmation. Also, can anyone confirm that they 'price bridge' like other major theme parks do?

TIA!

We bought the PTA tickets last year and used them. We were offered a second day for $10 upgrade because the PTA tickets are normal tickets.
