My week off in mid-September 10

Since I am no longer going to UK as I planned for almost a year, I am thinking of where to go and what to do during that week I am planning my personal time off.
I will be alone, which is what I want.
Maybe visit my aunt in CA for a couple of days, maybe go to NYC for a couple of days, and one more thing that has been on my mind is to go for a few days to one of those all-included resorts in Arizona. I've heard wonders about the location, the service is great, it is peaceful, relaxing...
I am brain-storming so far, and the ideas are popping up. During this time the computer will also be resting.
