What would you do to make it special?

Make sure you state, it's your first, 20th, etc, cause it's all different.

A long weekend away - Juneau, or Moraine Lake in Canada. Or closer to home (and smaller budget), Lake Tahoe - fantasy inn, or Las Vegas. Or - just stay home for the weekend, but pretend it is a vacation. Go do whatever tourists do when they visit your area, eat somewhere new, no chores for the weekend.
