I was on a theme cruise last month on the Summit. My cabin mate arrived too late (traveled from different cities) to have MDR lunch on the first day. Had to ask for the afternoon hors d'oevres and several times they didn't arrive - not terribly appetizing anyway. No special check in line. Concierge rarely available at Guest Services. Since we had a drink package, never did drink the sparkling wine so left it for our steward. No invite to helipad for sail away. In my opinion, not work the extra cost, especially on a theme cruise. And, if yours is a music cruise, like mine, you'll spend very little time in the cabin anyway. I've booked an inside for next years themed cruise. But, its a beautiful ship and we had a fabulous time - hope you do too.
