There are plenty of unscrupulous conference companies out on the great big world wide web. In this day and age of downsizing and layoffs I would concentrate on building valued skills via conferences verse saving a few buckks on a vaca. I continue to say, as someone who manages others schedules, use your education/conference dollars to enhance your careers and future and not to pad your vaca fund.
In case you haven't noticed, we are in a recession and bamboozling your DH's conference budget to fund your vacation budget could come around and bite you in the butt. Look for training that will enhance your DH's paycheck which will in turn enhance your DH's take home pay that funds your vaca pay.
Unemployment pay is way less and not the desired outcome for fraudently using company funds.
Lets all be nice here ...
I just want to add that as someone who used to work in marketing and participate in event planning, I know that one strategy to get people to attend your conferences is to plan them in places where people want to go. I've been to conferences in some very high-end golf resorts, spa resorts, casino's New Orlean's and yes DW, from both perspectives: as someone throwing the shindig, and attending as a conference participant. Let me just say, that when we had the conferences in nice venue, we got a lot of attendees. And by planning downtime for the participants, you encourage them to enjoy themselves, which further fosters a laid-back learning environment. Just because a conference is only 4-5 hours, doesn't mean it isn't jam-packed with material. Maybe with a medical conference that's the standard for the amount of technical information you can/should take in--I don't know. I'm just saying you don't know why something is structured the way it is, unless you are in that field.
I have a friend who's DH is a doctor. They love Boston, so that is the conference they plan on going to every year. The same conference is run in other places, but they go somewhere where they can have a good time together. It doesn't mean he gets less out of it, it just means he enjoys himself while he's there. There is nothing wrong with that.
Just this week, my DH, who is the total "company man" said he has a conference in Fort Lauderdale at the end on February, and let's all go a few days early and spend some time together. When he's at the conference, we will do other stuff, but we will spend time together during the conference too
(which is only 2-1/2 days). There is a boat trip one afternoon, and a golf outing. He doesn't play golf, so we will do something during that time.
It makes sense to tag a vacation on to the end of a conference--your costs are defrayed because the attendee was going to have his stuff paid for anyway. I don't see the big deal.
