Orchid 911

[NBCGLX]

Maybe I'm overreacting a bit, but I don't want to get to the downhill side of this mountain!

I keep my orchids at my office and I have been away from my office for about 4 days now. I made sure that I gave the orchids a good drink before I left and today, I returned to find that one Oncidium had exploded in flowers and the other is just about fully open now. Unfortunately, it seems that they have been craving water and I'm worried that this will affect them long term. I've attached a few pics below of the PBs followed by the blooms. What I want to know is, the PBs seem to be shriveled a lot, which I take it to mean they have been without water for too long. Am I misreading this and if not, will they recover on their own or is there something I need to be doing to be sure they recover. Also, will this affect them in the long term? They are gorgeous plants and I would hate to be the demise of them!! The pics were taken with my cell phone so they are not the greatest quality and the lighting is bad so the exposure is bad as well.
