With the addition of the advance reservation concept, it reminds me of the Fast Lane concept at many amusement parks. I dock very near Cedar Point amusement park in Ohio so I never saw the advantage to me of buying the Fast Lane pass at a premium because I can just go to the park on a quiet day. If I traveled a long distance to get there once a year I think I'd invest the $ in the Fast Lane to be sure I rode everything I wanted to. This seems like the same idea.

If I vacationed 1 week a year and spent $10k on a charter with a group of 8, I don't think I'd hesitate to guarantee my mooring choice for $12.55/person/night. Definitely a pricey option but I think it will sell and there is still the sharp heavy thing on the bow of all charter boats as an option.
