Anyone have any suggestions on how to find good vacation packages where the air travel component is done by Delta, but the destination is open to suggestions?

I find the DL site useless for this because I have to suggest individual destinations. But something like google.com/flights is only marginally helpful since it won't let me combine the flights + hotel. I find a lot of the major travel websites to be similarly restricted to destinations.

How do others here get around this issue? Thanks in advance
