Great Wolf has had four owners in the past decade. Most recently, Centerbridge paid an estimated $1.4 billion for it from Apollo Global Management in 2015.

“We have been very impressed by the evolution and growth of the company under Centerbridge,” said Tyler Henritze, who heads U.S. buying for Blackstone Real Estate. “Great Wolf has enriched the guest experience and opened seven new lodges since 2015.”
