Travelling Alone...?

Hey Fellas, Long time no see for a 'wee bit 
As some are you are aware, i start university in September and i've been working real hard this summer, lots of work. I work at a golf club, so even though because of the rain, when it is open, its bloody packed.
I've come to the summative conclusion that i need to get away for a good 9 days.
I've got many friends, no problem in that direction, BUT i'm sure you can all agree, is that when you and your friends have this great vision of going it away, it sounds good.. BUT... What happens in the end "Oh i cant get it off work" and/or "i cant afford it".
I've booked 2 weeks off work, i've got the money, and i'm prepared to go.. Exploring.. Alone if need's be.
I tend to do many things on my own, doesn't bother me, infact i prefere it because i get things done a lot quicker that way. Some people say its a bit odd, and even more odd that i should be off out on my own... but it really doesn't bother me.
I was thinking, regardless of all situation with friends, that i would like a good 2 weeks in the US. I've been to the US lots of times, but with my family.. So i would like to venture and see it myself for two weeks. I was planning on starting off in New York for 3 days, seeing the sites, then moving on etc. Eventually ending up somewhere warm.. Money isn't a great deal..i've been saving money like you wouldn't believe it!
So i would like some advice on travelling alone.. is it worth it? Whats it like? Also, places to visit in the US?
