Now if someone would make a temperature controlled - dehumidifier camera bag. Dual power, a/c for home and d/c while in the car and battery when outside. The camera bag could be equipped with a temp and humidity probe to control the environment inside the bag. Optimizing inside camera bag conditions to the surrounding natural conditions. To a degree!

When it's less than 15k, I'll be in!

Sometimes it's just not appropriate to snuggle your gear in public. That's why I'm offering a more organic approach. :) |
I think you shouldn't worry about what other people think is appropriate and just express your undying love. |

DO you have any idea how -2C and the word cold just don't seem to go together to a Canuck like me...that is almost a balmy day here.

If coming in from a cold shoot, patience is key. I usually keep the camera in pack. Taking it out to download, an hour or so later. In a rush, I will unzip the pack. Still leaving it closed, yet slightly open to breath. Maybe cutting 20 minutes. The camera is still very cool, but has produced no condensation I can see. So I'm thinking this could work in reverse for you. In your case, the key is controlling the speed of warming. Does the hotel have wine boxes? What about a box with pencil sized holes poked through it. Placed within a larger box, with the same holes.
Producing an air gap, within the box. Then you place your gear inside. I would think this may act as a semi insulator. Slowing the shock of warming. Do you have a rental car? Use the ac/heat to indirectly warm them up gradually. Worst come to worst, you look like you're moving. Just throwing some fun ideas, but hopefully helpful.

If you are at or near a beach, you can get antifog for diving masks at any dive shop. It's basically dilute citric acid, but it works. Try to keep it out of the working parts.
Try laying a very dark medium sized towel out, as flat as possible, on the dash, where it will get warm and very dry in the sunlight. Take the camera out of the bag and wrap it with the warm dry towel when you get to the car from the cold room. The warm towel will help warm up the camera quickly, without risking damaging it, plus keep it dry as it warms up. The towel on the dash will get quite a bit warmer than ambient temperature, even with the A/C going if the sun is on it.

| How far of a drive do you have to go, Michelle? As Richard suggested, the hair dryer is a good idea. You might also just place your bag open at the passenger side footwell with the heat turned up. |

Me too, just a short drive along the 416.

I don't think this hotel will have wine boxes, and I'm not much of a wine drinking and don't have any either. Interesting idea with the isolated box, but not sure it will be workable for us. We likely won't have a rental car (but it's possible). Most likely we'll be taking a shuttle from the hotel. Not much control of our surroundings at all.

I'm not sure how far of a drive it is, but my guess is 20min on a good day at least. It should be sunny, so I think our best bet is somehow getting them as much sun exposure as possible on the drive there (similar to what  MelonMusketeer said). I'm not letting this heated rice-bag/pie-weight-bag idea go just yet though. Gonna do some exploitative shopping this weekend. |

Moisture comes out of a heated rice bag. Try heating one up, and hold a clear filter or mirror over it and you will see the condensation forming. It will warm up the camera, but it's very damp heat coming from the bag.

The same thing would likely happen with the clay pie-weights, eh? |

This is a very good point. In fact, to add some further information (if not already posted):
Often, I take my camera out in the cold winter air to shoot the sky either on a tripod, prime or projection work with the telescope, or just some nice outdoor shots (day or night). Before bringing the camera back into the nice warm, and sometimes moist house, I put the camera in a plastic bag OUTSIDE and let it equilibrate to the room temperature before opening it to avoid the condensation.

Yep, fog happens! ;-)
The technical reason is that the temperature of the lens is below the dew point of the surrounding air. The most effective method of avoiding it is to use any method you can of keeping the camera at (or slightly above) the air temperature, in which case there can never be any fogging.
Attempts to wipe off the condensation will just result in more condensation forming, so not really a solution. As previously posted, keeping the camera and camera bag out of air-conditioned spaces, thus avoiding fogging altogether, is the best solution. It's not always practical and sometimes risky (theft, overheating), however.
Keep in mind that if fog is forming on the lens, then it is nearly certain that condensation will also be forming inside the camera, e.g. sensor surface, mirror, electronics... this is not a good scenario. It's very clean water (distilled, by definition) but will cause temporary and/or permanent shorting of electronics if it remains too long. |

| You know those little desiccant packs that say "do not eat" that you get with every pair of new shoes? I keep a couple in my camera bag and rarely have trouble with fogging in humid situations. |
