Our team is thinking of doing a "Project In A Week" (bootcamp), and I'm interested to know if anyone else has experience of doing this or has any advice?

The idea behind it is to get away from the distractions of the office, motivate each other, and build our bonds within the team, in order to come up with an innovative and profitable product in a short space of time.

The plan is to get the whole of the dev team (about 5 devs), a designer, a project manager, couple of sales and marketing people staying in a conference centre/hotel for a full working week. We'll be completely focused on building one web app (planned in advance) and getting it live and on the market within the week. We'll work quite long days but in the evenings we'll have some fun together as a team. There would be a couple of members of the team left in the office to ensure we're not distracted by day to day client support. Similar 'immersive' approaches are used by training companies such as Firebrand.

Good idea? Terrible idea? What should we do to incentivise the team?

Any thoughts/experiences/advice would be greatly appreciated.

Cheers
