If you've ever done any business travel, you know that a week's worth of laundry (Two Pants, five shirts, six pairs of t-shirts, socks and underwear) through the Hotel - usually goes for about $200-$225. If you are thrifty, and order a service, and are willing to wait for a week's delay, you can get your laundry done for about $100, but then you need to juggle logistics of actually getting your laundry to the service and back (and then worry about having to leave early, and stranding your laundry in a remote city)
If you are a freak (like me) - you actually track down a local laundromat, and burn a couple hours on a Saturday Morning doing your laundry to save the company $200, but 95% of business travelers just throw it on the company tab.
My advice to Prim - If they haven't already, reach out to Casto Travel (Typical corporate travel agency) - and every similiarly focussed travel agency, and see if they can get traction with the business travel market. You won't make any friends with the Hotels, but when I see a $250 laundry invoice for a single bag of laundry, I can't help but think that's a market ripe for disruption from below.
