Nikon d300 humidity problem?

I have a shoot tomorrow in an indoor swimming pool. The walk to the swimming pool takes me about 8 minutes from where I live. My question is, should I be expecting humidity problems. I'm planning on getting there ~1h earlier to let my camera aclimate to the indoor climate and then move on to the pool.

I have heard there are some tricks I can use such as separating the lens from the camera body and putting it into a zip lock bag, same with the camera body.

Also, bringing a blow drier along, I heard was a good idea also.

Any tips?

I have an Olympus E-520.It was cheap 5 years ago. When I had to do the same thing, bike across town to shoot a pool in winter I was worried. But I had no problems. Just put a silica pack (the do not eat thing in new shoes) in your camera bag and you should be fine. That $2000 workhorse should have some sealing to be able to make some claim about being able to do humidity.

If it's cold outside (around freezing), put the camera in a plastic bag, wrap a jacket around it so it stays warm while transporting it (quickens the acclimatization to indoor temp). When you get to the pool, remove the jacket wrap and let the camera warm up while in the plastic bag. If it isn't that cold, you probably don't need to do anything special.
