I wish Great Adv. -and SF in general-would renovate the parks like what they did to the area around SFA's Wild One.That area was a dead end with basically a classic coaster,a so-so drop tower and lame themeing.Now it has a cool new theme,more rides,an adult beverage area and has an alternate route to Gotham.
Great Adv. could do the same,in most cases just by altering paint schemes and ride names.I think they should start by making Old Country and Movie Town into one section called "Warner Bros. Studios" and having some sort of live music show in the theater.Another do-over would be the whole Boardwalk area:I think it should get an Oceanside/Jersey Shore retheme with S:UF being renamed the Jersey Devil and Green Lantern getting sit-down trains and a shark theme and being renamed The Jersey Maneater.And the motion simulator theater could be renovated into a "flying theater" that showed custom films during different seasons.
And as far as hotels go I think Great Adv. should get their own franchise-like a Best Western or Comfort Inn,and it should have on-site restaurant(s) and nightclub(s),with the possibility of adding casino space.
