We live in New Orleans and have cruised on both ships. Had a great time on both but prefer the Grandeur for its classier decor and slightly more upscale atmosphere. The Conquest had more dining and entertainment options than the Grandeur but the food and service were better on the Grandeur. The Conquest had larger cabins but the ones on the Grandeur had more storage spaces. The average passenger age on the Grandeur was noticeably older than on the Conquest and there were fewer kids onboard. The Grandeur was more stable and rocked less than the Conquest, even in heavy seas. I will be cruising on both ships again this year and I would not hesitate to recommend either one. Make your decision based on price. If they're both the same price for the same week then I would pick the Grandeur.
