I agree with Alikat - if I was quilting something designed for bed use and not for show, I would not quilt it that densely. I might if it was a wall hanging.
Are you planning on making up some samples to practice on first? Get some scrap (ugly) fabric, make a quilt sandwich with batting, and quilt both densely and sparingly. This will help you decide what you like best and also give you a chance to adjust your tension, etc.
Good luck!
