Why not consider doing something completely different for a part of the building?
Consider operating a stationary urban cruise ship and market all-inclusive long weekend or week-long vacation packages to hotel guests. Offer them a spa, fitness center, specialized shops, a live theater, a reading room, swimming pools, wall climbing, surfing pool, water rides, children’s activity center, live theater, game room, lounges with live entertainment or sound system, basketball courts, miniature golf, video games, make available for sale tickets and transportation (i.e. shore excursions) to Niagara Falls, Buffalo Bills football, Buffalo Sabres hockey, Harbor Cruises, Albright-Knox Art Gallery and Burchfield-Penny Art Center, Buffalo Zoological Gardens, etc.
Inquire of the cruise lines or Disney to learn their interest if any. One of those companies might be interested in operating such an enterprise.
And also offer these amenities to non-guest day patrons desiring 4-6-8 hour personal, couple and family activity passes.
I would guess that due to the local economic climate in the Buffalo-Niagara Falls Area redevelopment of this property could qualify as an EB-5 project for foreign investors seeking to move to the United States.
It never hurts to ask the questions and the worst that can happen is the project isn’t possible.
