To add to the list of reasons why this WOULD work (if done right)
MVMCP/MNSSHP/MPPP $50
Keys tour $60 Backstage $200
Dive in The Seas $150, Aquatour $100
Sunrise Safari $55, Sunset Safari $150 + required AKL concierge stay
All of these current programs are very popular...so why wouldn't a greatly expanded Sunset Safari without need for concierge stay not work.
I'm not saying that this is necessarily my personal preference for the next expansion/capital expenditure. But I have NO DOUBT that it will be successful.
I hope I am around here long enought to hear a heated discussion on why an idea might work and might be successful instead of why it is sure to fail!
