One more Spain question?

I've always wanted to go, researched this country for years, and I've decided this was the year. I applied to study over there and was accepted, but unfortunately I had to change my dates because money was a problem.

I have the option of going either in October or November now (to study there), and I have to make a decision within a few days.

I'm leaning toward October, but the one reservation I have is that if I wait until November to go, then I will have more time to save money.
Also, airfares are a little bit cheaper.

One possible solution that ocurred to me :

From what I've read, and been told, October is an ideal time to go, and if I commit and decide to study there in November, I'll always have the option of going a few weeks early, in October, should I find a way to get more money or get a good deal on a plane ticket.

Here's what worries me: I don't know anyone to go WITH me. I am not worried about going over there to study, because it's part of an organized program and the school will help you find housing. I want to travel and see the sights, but I'm not sure if it's a good idea by myself. If I'm going to go off sight-seeing, I would rather have someone to go with me, but I don't know anyone who is able to go.

I would like to know some possible solutions to this dilemna, please?

I'm definitely going to Spain, going to study there, but I'm not sure what to do about this dilemna.

Thanks if you can help me.
