It seems to me it is a reasonable expectation that a hotel has thick enough walls to provide protection against loud snoring. Both you and your neighbor should be complaining loudly to management of the hotel about the inadequacies of the walls. In the mean time perhaps ear plugs for both of you is the only workable solution. Him so he doesn't hear your snoring and you so you don't hear his banging. I don't like listening to loud snorers either but it seems to me you have a god given right to snore in the privacy of your own hotel room.
