Well, from when I used to go camping years ago I recall that dew does 
seem to collect more in open areas than in covered areas, at least when 
the air is still.  Thus, if you have a canopy that covers your observing 
area plus a least one side to block the prevailing winds you may be 
ahead.  Of course you would have to confine your viewing to avoid the 
zenith and/or keep moving the overhead canopy as you would rotate a dome.
