Tips for booking the best hotel deals - Why it pays to use memberships

While loyalty club membership typically garners travelers extras or upgrades, discounts on room rates may also be available to members of large groups such as AAA or AARP, Winship says.
For example, more than a dozen chains, including Travelodge, Clarion Hotels and Comfort Suites, make special AARP-approved discounts to members, says AARP spokeswoman Allyson Funk. There also is a website operated by the hotels and companies offering the AARP discounts that you can reach through the AARP site.
Check with any of the groups and professional associations you may be a member of to see if they have discounts available on hotel room rates.
