MPA@LSE vs. IPP@UCL

Hi
I had applied for MPA at LSE and International Public Policy at UCL. I have received an offer letter from UCL. I am still waiting to hear from LSE. I would appreciate it very much if someone can help me decide if I should accept the UCL offer? Specifically I am looking at the following questions:

How good or bad it is to complete IPP in one year at UCL vs. doing two years at LSE?

UCL scores higher on Times ranking but I am not sure how good it is for IPP?

It is cheaper to do IPP at UCL (£27,000) than LSE (£62,000), all inclusive. How much weight-age should I assign to the cost factor? I know it depends how much I can afford but still in terms of return on investment, what do you guys think?
