Don't worry about telling Tiffany what time to pick you up. They hang out in the parking lot and talk to each other before folks debark. On our cruise we told him to come at 9am and he said "Oh, you'll be off way before then". I told him we were going to just walk around the ship for as long as we could since our flight was late. He said he was going to come early anyhow. Needless to say we didn't debark until almost 9! Just tell them you need a pick up after the cruise.
