I appreciate it's more money and thus a bigger gamble, but I always find staying one night in a hotel a bit counterproductive because of the checking in and out issues. If you stay 2 nights, you get many more working hours, and you also may catch a client on Day 2 who couldn't do Day 1. So, I'd be tempted to tour a little less, but stay for at least 2 nights, and advertise the fuck out of it beforehand.
