How soon to do destination wedding cake tasting?

My Fiance and I are planning a wedding 600 miles from where we currently live. We will be going there next month, is that too soon to do cake tastings for a wedding that will take place Spring 2011? If we went a month before the wedding, would that be too short notice to have a cake made for us? And if anyone knows of a good bakery in San Diego, I would appreciate suggestions!
