Royal Orchid Plus members who rent an Avis car anywhere worldwide for three days or more before May 31 will receive a 15-percent discount, in addition to 500 miles. Book online at http://www.avisworld.com (Side note: The avisworld.com Web site has recently eased one of the headaches of frequent travelers — missing miles. Too often, miles earned with program partners are not properly credited, and trying to track them down can be a real problem. Now, claims for missing credit can be submitted directly online at avisworld.com.)

Also until May 31, Royal Orchid Plus members will earn double miles and receive a 30-percent discount at Central Hotels & Resorts throughout Thailand with any stay of two consecutive nights. In addition, members will get a 10-percent discount at all hotel restaurants, and a 10-percent discount at Centara spas.
