Hi Christie i am doing that same tour and will be in NY a few days before after my Grand Southern Tour i will then be in LA for a few days after before i head off to San Francisco
I will probably be in LA for 3-4 days, i will be there before i start my grand southern tour but i probably wont be doing much then due to jetlag, so i will most likely do the theme parks when i finish the grand northern and i will be in the same boat as you as im going by myself
