Carlson Hotels Launches New, Cross-Brand Loyalty Program
(Posted: Jan 12, 2005)

Say what you want about Minnesota winters, but don’t think that North Star Staters are idle while the snow flies.
Minneapolis-based Carlson Hotels Worldwide (think Radisson, Park Plaza and Country Inns) has just announced the launch of a revised loyalty program, goldpoints plus.
Of course, all of Carlson’s hotels have had loyalty programs for some time: Radisson had Gold Rewards, Country Inns had Gold Points Rewards, and Park Plaza had Park Rewards.
The new program draws all the previous schemes under one umbrella. Members of goldpoints plus can now earn points at Radisson Hotels & Resorts, Park Plaza Hotels & Resorts, Country Inns & Suites By Carlson and Park Inn locations worldwide. This includes all the Carlson-affiliated hotels in the Americas, and partner properties operated by Rezidor SAS Hospitality in Europe, the Middle East and Africa.
That bears repeating – the new program is slated to cover all SAS properties. For years, a common complaint from members has been that Radisson’s program lacked continuity in international markets. Members had difficulty with both earning and redemption at European properties. That problem, it would appear, has been solved.
Another major change is the way in which members earn points. Previously, Gold Rewards members earned a flat 1,000 points per stay at a Radisson hotel. Now, members earn 10 points per dollar spent at stays at all Carlson properties – a much more familiar standard for frequent guest programs.
Carlson was also formerly criticized for the lack of an elite program. Not until March of 2003 was an elite program implemented. The new program improves upon that, offering levels of membership: Base, Silver Elite and Gold Elite. Silver Elite is reached at 5,000 points; Gold at 10,000. Upon reaching the elite tier levels, guests will earn 50 percent and 75 percent bonuses respectively on the points earned on hotel stays. Elite members will also have additional reward privileges, such as the option to convert points to a major credit card rewards program.
And of course, goldpoints plus is a part of the Gold Points network, which, loosely translated, means that members can earn and burn points with over 1,500 participating merchants.
