What is the BEST sunless tanner?

use a tinted moisturiser to build up a tan slowly - this is the best thing for fair skin. Once you've built up a tan using that, get something like Piz Buin airbrush spray or Fake Bake tanner in the light tones - using a darker one will make you look silly if you're naturally fair. Spray tans are also really good but to be honest whatever you do will only last a few days - a week unless you continually reapply so maybe it would be better to wait until may to start.
