That sounds logical, but really - you can do a long weekend to almost anywhere in North America and some Caribbean sites.Usually, I'd rather do at least a week long trip, because of flight time and down time to fly.
But, if the destination is close enough, the work schedule doesn't permit a week or more off and I'm desperate to dive, I consider the long weekends.
One approach for me:
Fly to Miami on Thursday
Dive Friday, Saturday, Sunday
Fly back Monday
I do that from time to time, and - you could, too. Probably spend less on the plane ticket than me, as well.
My suggestion is that holiday weekends like Memorial Day and Labor Day are idea for me to do long weekend. I'd rather do them with SD.com
