Up here in the Pacific Northwest, I don't recommend students remove their wetsuits in-between dives unless there are a great number of hours in-between (i.e. morning dives to a nigh tdive timeframe). For shorter surface intervals, I would think you lose time and you'd get more chilled completely removing the wetsuit. As was posted above you're core will not re-warm to standard temp.
When I am wetsuit diving, after getting out of the water I will immediately put on a fleece cap that comes down over my ears, then a large fleece right over my wetsuit (b/c it can ring out quick anyway), then a rainproof jacket (non-breathable to cocoon me and keep the body heat I do have), and fleece gloves. I also pack a fleece scarf, and those hand warmer packets you can pick up from REI too and use them when necessary.
My goal here is to preserve the body heat that I do have. If I am able to get somewhere with a heater, then I would seek it out. If not, like when I am boat diving, I cover up as indicated and stay out of the breeze.
