To paint or not to paint?

I went by my booth today for some major clean-up and to get rid of the last Christmas leftovers.  I spent about an hour tinkering around, putting in new stuff and rearranging the old.  And as much as I love puttering about in my little space (no kids, no work, no phones, no nothing - pure bliss), I am getting increasingly annoyed with the horrible walls in my booth.  The brown paneling is getting on my nerves and the white back wall is grungy and full of old nail holes.  I checked with the owner today, and she said I could paint anything whatever I wanted and that the next couple of weeks are usually slow.

Dreary background, but my colorful toy section is spreading - and my sales have increased.

So, what to do?  Should I attempt to paint my space even though it is full of stuff?  Should I do it in sections?  Or pack up everything, do a fab paint job, let it dry, and then stage it all from scratch?  Have you ever done a drastic paint job AFTER you moved into your booth?  Any advice?

Finally, what do you all think about a light aqua color? Perhaps with white shelves?  Would love to hear what you have (or have not) done, and if it helped your business.
