We were going to stay at the Dolphin (our favorite hotel!) this spring, but with 3 adults and 2 kids, the extras were just too much, so we switched to 2 rooms at the Pop Century. It was $25 per night extra for the 3rd adult, PLUS $25 per night for the rollaway, so and extra $50 per night offset the wonderful teacher discount. We are flying in so couldn't really lug an air bed.
