> I'm sure there will be fees.

Those fees are going to be in the neighborhood of $40k/year. I couldn't find any good documentation, which I suspect requires going through more of the sales process. However, this page [1] has children's rates as $15-20k/year, and another article suggested around $25k/year for adults. That's assuming double occupancy though - single occupancy gets an 18% discount off the rates for double occupancy.
