From our condo in Hawaii - actually it wasn't the greatest experience, I had to get up at 4:00 AM, and the during the 2 week period my performance was awful. I'm of the opinion that the correct trading mentality if a fragile thing, and changing the environment can throw things off.
For example - mondays are my worst trading day of the week (taken from 9 months data) and I suspect it's because I'm rusty from the weekend layoff.
