Planning a journey

Dear friends,

Since a while I'm For some time I have been planning to visit the United Kingdom as I've never gone been there before. I'm planning to have a journay of visit for about eight days, but I'm not sure how I will spend them.
My wife wants to go in to London, but stopping over there would require at least four of five days. Instead I'd like travel around the Midlands, so I don't think we will have not so much enough time to do both.
Although I guess the London visit is inevitable, beacause as a husband I can't  avoid to accomplish ignore my wife's request (you know how do the women are ...). So, in order to save do it both ways, I think we'll stop in London for three days, then we will rent a car and will start to travel to the North. I don't know what towns are better to get the best to visit, maybe Cambridge, Birmingham, York, Leeds and Newcastle.
If you have any advice for my journey, I'de be glade if you told me. to hear your suggestions.
Thank you!

Good job for the most part, I understood all you were saying.  I just wanted to offer some different corrections than those already posted.  This way you have a few different ways you can say the same thing. With English its going to vary from region to region on what sounds natural!
