Often times, I stay 1-2 weeks in a hotel, and I find that the Virutoso rates sometimes offer a hotel credit per stay. That credit (usually $100-200) is flat, no matter if you stay one day or 10.

I find this a bit strange since it encourages you to stay for a shorter period in order to maximize the credit. It makes more sense to split a longer stay up between a few hotels, rather than staying loyal to one.

Is there a way to negotiate this credit directly with a Virtuoso agent or even the hotel directly for longer stays? Have people had any luck doing so?
