At its conference in Las Vegas, IHG said Staybridge Suites and Candlewood Suites will get new exteriors with front porches to create a welcoming feel, public areas with shared workspaces, social areas, breakfast spaces that can be converted into a lounge area, and new suites with more distinct zones for working, relaxing and sleeping.
Candlewood Suites, which has properties in the US, Canada and Mexico, will also get a new logo.
Heather Balsley, IHG's senior vice president, global marketing mainstream brands, said: "We are continually evolving and investing in our brands, and at the centre of our latest enhancements sits extensive customer research and close collaboration with our owners. This is crucial to delivering brand experiences that fit the ever-evolving needs of mainstream travellers and drive performance for our hotel owners. As these new prototypes start rolling out across the market, we know they will take guest satisfaction and brand strength to the next level."
IHG also announced its new extended-stay brand Atwell Suites at the conference.
