I want to also reiterate it depends where that group is from- like Las Vegas, In Cancun foreigners or people in general think that suddenly no rules apply and need to be reality checked prior to entering as you mentioned. Not all bachelor parties are disrespectful idiots!!
I have no ideal why TTR even let's mass groups of single guys in. It just. Ruins the party TTR feels like a couples resort with a fun spring break vibe without the ass holes.
