There are plenty of Holiday Inn in my area and I’ve earned over 5000 points so far by checking in via Foursquare.
Lucky from the One Mile at a Time blog points out that TopGuest had added more hotel and air partners now. You can earn 25 points per day with Virgin America at terminals or baggage claims, 50 Wyndham points at Wyndham hotels, 50 Choice points at Quality Inn, Comfort Suites, or Cambria Suites and 50 Hilton points at Doubletree hotels. You are limited to one check-in per day.
This is one of the easiest promotions out there – take advantage of it!
