The direct route into IHG Gold Elite is card spend, not a free trigger: put $20,000 in purchases on the IHG One Rewards Traveler (Chase), a US card, in a calendar year, and IHG One Rewards grants Gold Elite status through December 31 of the following year. That threshold only makes sense if you're already routing that much spend through the card — but once you clear it, everything downstream is free.
Wyndham Rewards will match Gold Elite to Platinum at no cost — the match holds for 90 days, and four qualifying nights within that window extends it. The same Gold tier also feeds a longer, free chain outside hotels entirely: it matches into
MSC Voyagers Club Silver, then from there into
Explora Club (Explora Journeys) Silver — both once-per-lifetime moves that the reference below maps hop by hop.
