Okay, I'm shamelessly cribbing from my 2005 MSP proposal, just to throw something in the ring. If people want me to follow through and get more info, please let me know.
Minneapolis Update:
I've concentrated on the downtown area, as that is the place that has the best hotels with the most to do and the best public transport.
Hotels range from $109-159. I've put in a request for a group bid, but I've not gotten the information yet.
Public Transport
The Light Rail runs between the Mall of America/the airport and downtown Minneapolis. Light Rail and buses are the same fare - $1.25 for 2.5 hours ($1.75 weekday rush hour) - and go all over the Cities.
Taxi rates are reasonable, but taxis can be difficult to find once you're out of the Downtown area or the airport. They are all over Downtown.
Eating and Drinking
There are restaurants everywhere. All kinds of restaurants, from the hole-in-the-wall Vietnamese soup place to three Irish pubs within spitting distance of each other to good Tex-Mex to barbeque to Thai to chi-chi American to French.... I can easily go on. One of the best places to go for food is along Nicollet Aveune just out of Downtown. It's called "Eat Street", and it has, well, everything.
There are also bars everywhere. Prices are middle-of-the-road - bottled domestic beer, $3; vodka tonic, $5; specialty martini, $8. This will naturally go up or down, depending on where you go.
Shopping
Holy moley, is there shopping. Minnesotans love their shopping, especially at a discount (no sales tax on clothing!). Hence, I offer you:
The Mall of America and The Albertville Outlet Mall.
There is also a heck of a lot of shopping downtown, including the two-level Target.
But wait! There's more!
Other attractions include:
The most live theaters outside of New York City
A ton of galleries in downtown
The Foshay Tower
The Sculpture Garden
The Walker
Minnesota Zoo
Valleyfair
Ground Zero, home of Bondage A Go Go (meara's been there)

An extensive park system, with trails all around the city.
Steamboat rides along the Mississippi

The Quest - the club formerly owned by Prince
Speaking of the Purple One, Paisley Park

Airline Prices
Booking early is best, as NorthWest likes to screw people over if it can. Current prices are ranging from $200 - $400.
Weather: Average high for early May is 72 degress, average low is 50. It's generally pleasant late spring weather - mostly sunny, a few showers.
I will be happy to provide more in-depth information as requested.
