I think the cost was so astronomical that there was no way this could work. Who wants to pay $125 for a boat ride? I went on a 5 night cruise for a little less than $100 more than that, back in January. $10 pp would be much more reasonable.
Oh yeah, that cruise included a $100pp ship board credit, so essentially, I took a 5 night cruise for $6 less than a, what, 20 minute boat ride around that lake.
