Here on Carnival you have an option. Well its really not an option but like if u refuse to go ur cabin steward will give you a sheet that states that you refused to go to the drill and that u have read the evcuation notices and policies which u will sign. Every time we have been onboard with RC, we have had our cabin checked off. On carnival, every cabin is fully checked and a red "Evacuated" tag is inserted into the lock. I agree that the drills are a bit annoying but u need to remember that there is a reason that these drills are mandated by the Coast Guard and performed by the ships for a reson, for your safety. The best thing to do is just go to the drill because every person that doesnt go makes it last even longer.
