John EmeighBUTTE (KPAX) - Fairmont Hot Springs is planning a multi-million-dollar upgrade to the pool area that will make it look very different. The investment is about $8.5 million to replace the existing pools with six different outdoor pools and, after that, two new indoor pools. “It's a little different when the place was built in the 70s, where, you know, one large, Olympic-style pool was the trend. Now, the trend is a variety of different pools and different shapes and a variety of experiences,” said Lubeck. Fairmont no longer has day passes, but it does say memberships for three months, six months to an annual.
