(virgin) Margarita Recipe for LARGE crowd?

[C♥H♥E♥E♥R***Girl!]

i'm having my sweet sixteen soon and so far theres about 50 people coming. its mexican themed and i wanted to find a margarita (virgin) recipe or margarita punch recipe that could serve a lot of people. help please?
this will be served in a punch bowl so guests can serve themselves btw

yes- i asked this question the other day and got one recipe i want to try- but incase it doesn't turn out i wanted to find a different one.

Just buy one of those Margarita buckets and don't add the tequila.
