Received an upgrade on the Conquest to a Cat. 11! It was great! Very roomy. The bathroom was the best as it had dual vanities and a jetted tub. Also there's a dressing room seperate from the bathroom. Makes it much easier when it's time to get dressed for dinner or in the mornings. I didn't use the Skipper's Club boarding though. I didn't see any indication of it. It seems like maybe you have to ask for it when checking in.
One thing- on the Conquest there were VCR's in the Cat. 11. I didn't know that before hand and took no tapes. I never saw any facilities on the ship for checking them out. So, if your Cat. 11 has a VCR you may want to bring a few favorites from home.
