I would definitely say main beach... if you gotta go AI pick GP or another near the action (Legends?). I agree with the person who said to pick a place based on what they offer, not the people you hope will be there... just cause you never know who will be there! He can always venture out to meet people!

I like the idea of Alfreds as it is in the middle of everything (if he wants to really live it up). If he wants a more chill spot as a homebase, I gotta throw my favorite White Sands into the mix.
