Where are some affordable vacation spots?

I am looking to plan a trip with my husband for later this year, probably sometime in September. Where are some great destinations that have nice beaches? We live on the west coast and somewhere that wouldn’t take days upon days of flights would be nice. We’ve been to Oahu, Hawaii and various places in Mexico although we wouldn’t be opposed to going again.

Where are some affordable vacation spots at the moment? What about all-inclusives, are they worth it?
