Typhoon Lagoon locker question

[Aaryana]

I’m heading to Typhoon Lagoon solo tomorrow. I was planning to rent a locker to leave my bag, but I’m not sure it will fit. Does anyone know if a baby Bogg bag will fit in either size locker? I see the measurements but depending on how the locker is shaped, I’m not sure if it will work. Will I be allowed to carry my phone onto slides and in the lazy river? It will be in a water proof pouch. I don’t want to have to constantly go back and forth with to the lockers to check my phone. Thanks!
