yes, worth it.
I used them around a year ago. There were some problems, mainly becuase I asked them to organize the transfer of points from Amex MR->Starwood for me, and many of the transfers didnt come through on time. Even though this was the fault of Amex or Starwood (they both blamed each-other, of course) because I know the request was made on time, the people at Awardplanners still refunded my money WITHOUT ME EVEN ASKING. That's customer service.
So I would say-> go with award planners. they'll take alot of the "waiting-on-hold" time and minor details off your hands. Just make sure you give them enough advance warning of your plans to avoid unforseen problems.
