Is there any advantage in booking directly with Couples vs Expedia?
If you booked through directly Couples, you'd probably have more a bit more leeway in case you should see a better deal come up before you go, or in case you need to change or reschedule your dates for any other reason.

I prefer a discount travel agent. We get a better price then Couples or Expedia to start, and she gives us the better deals if they come up.
If you book direct at Couples, changes are easy and you can pay over time. At Expedia, I think once you book it can be costly to change, upgrade, or take a better deal.
We book our air and motel separately for we can make changes. Packages sometime lock you in and you can not change at no cost.
