Waxing??

Hi girls! So I'm going on vacation with my boyfriend to a beach and id really like to go get a Brazilian wax... I always shave now...
But I'm kinda nervous! I have very course hair and I know that will not feel good. Also.. If I do, will it be red or anything for a few days? How far in advance should I get it done? And how quickly does it grow back? If I shave it will start growing back the very next day 😒
And insight would be awesome!
