I say 2 confirmations not 2 hours, just wondering because 1 confirmations needed (to avoid RBF) or 6 confirmations (to ensure it's impossible to double spend) so why two.
I haven't seen a "normal" chain reorg with the abandoned loosing chain branch being longer than one block for a long time now. Thus waiting for two confirmations seems almost safe enough to me. It's basically the smallest amount of confirmations that you would stick to without taking too much of a risk.
