Hello! First let me say (type) any input is helpful! I can't decide

what to do I want to go to disneyland soo bad don't know why but I do

i'm a east coast girl and been to the world I think every year of my life. heres my dilemma
I can go with a friend in august waiting on her final ok.. she isn't sure about her vacation. If she can't go then i was going to wait and go in november for my birthday but then i would have to go alone. Soo I don't know if I should wait and go in november which seems less crowded. Oh and since this will be my first visit do I do the disney hotel or stay at a good neighbor?
please any input would help I need fellow disney input lol
THANKS!
Beee
