Therme's spa and Ecorecero's adventure park will have to continue to reinvent themselves to stay viable. There will come a time when their novelty will wear off, and both will see a decline in attendance. It happens to every venue of this type. It happened to the original Ontario Place, CN Tower, Wonderland, Mairneland and so on. Will they survive for any length of time? Depends on how much they want or can invest into their reinvention. I give them ten years before they're redeveloped. Live Nation will survive because their offerings are ever changing and appeal to everyone.
