I have been on the Mariner and Splendour for Rcl and The infinity for Celebrity. Summitt which is sister to Infinity would be quite a bit smaller than the the ships you have sailed but will feel just as big and not near as crowded.. It has just been refurbished also and from all accounts very well turned out now.As far as an older crowd on longer cruises likely that would be true shorter ones not so much. I can recommend the ship and suggest you can not go wrong and think that even at such a young age you will enjoy the experience.
