First timer for Mexico this year. Wondering how hard it is to secure party favors while at the resort?

Folks have indicated they bring their own shit with them from those I’ve spoken with, but I fly internationally for work regularly and can’t really risk some sort of incident preventing my ability to continue to do so in the future.

Can someone assuage my anxiety around this? And I am not interested in any sort of hullabaloo outside of that, thanks fam!
