Hi ​@samoanprincess unfortunately there is now way to restrict a Product in this way. Please upvote product restrictions – Welcome to the Product Ideas Forum 😀  

Hi Christina, as Sanne mentioned, there is currently no option for product restrictions, however, there is a way to achieve the same by having a separate rate-plans.

You can create duplicate rate-plan with the same specification of your current one, and set the permanent restriction

for rate A: Maximum length of stay 1 night

for rate B: Minimum length of stay 2 nights

Then you can set the product rule for rate B to add product “Green choice”

This way these 2 rate-plans will never be displayed both together as when one is available the other one is always restricted. Pricing of the rate-plans can be linked to each other, and addittional restrictions can be handled on the level of Rate group so that you can avoid having an extra steps when managing the rate plans.

I know it is a bit complicated way but currently I did not find any easier one to achieve adding length-of-stay based products.

also thank you ​@Sanne for sharing the link for upvote of product restrictions. It would be great to have that in Mews.
