I am currently an Accounting major and thinking of double majoring?

I got to the University of Houston. I am working on my B.S. In Accounting. My plans after getting my Bachelors is to go work as an Auditor for one of the Big 4, while i work on my CPA Qual's. But... i am thinking i might be smart to double major in Accounting and Finance. I love financial accounting, Way more than Costing, and Taxation. If i were to double major in Accounting and Finance, i could open my doors to being an IB, CFP, and CPA... more wall paper i guess. The core cles are the same and i will have to end up taking an extra semester to receive my finance degree. So any of you professional business people out there have any input on this? Is it a good idea? Or will the Accounting degree be enough?
