Hyatt acquired Two Roads hospitality and its brands late last year (read more here) and roughly third of the hotels decided not to continue under Hyatt and have rebrabded.
Thompson Hotels already became World of Hyatt participating at the end of March and today (May 15, 2019) Joie De Vivre-hotels are also part of the program.
You can access Hyatt’s page for Joie De Vivre here.
Here are the hotels:
Joie De Vivre only has hotels in four states in the US and none internationally. It is good, however, for World of Hyatt members to have more hotels where to earn and redeem their points.
