We only want to offer meals on dates that our kitchen team are open (we do not have a traditional restaurant as a retreat centre) and one off experiences on set dates - please add this feature.

I want to add special dinners that are available only certain days of the week. So this is critical for me.

This idea is here since (AT LEAST) 2018: Look at the last visible comment:

Restrictions are a great tool for managing your inventory. Currently, restrictions in Mews are only applicable to rates, however expanding this functionality could allow you to apply restrictions to stay products. This could create much more flexibility as you create packages and promotions for your property."

It was almost 6 years ago that restriction to product is being ask.

Please add this new feature, it will greatly help us!

Needed please :P

Please add this feature in! It would be very helpful

Package Restrictions like you have for rates would be great !

...and the option to restrict product with a specific amount per day (like limited parking spaces)

Hey Mews, there are multiple requests for product restrictions.
How about gathering them all together? (and adding the requested feature to MEWS)

We want this too.

For example to restrict which room types be booked by visitors with dogs (dog = product added to room.) and how many dogs (max amount of dogs to be added to room).

Apply the same restrictions that exist on rates to Products

Yes, we need to be able to limit products on the booking engine! We want to offer flowers, but only to people booking at least 24 hours in advance (it can't be arranged same day). We want to offer late checkouts, but only on our standard rooms (we can't do late checkouts on suites), etc.

Promotions can often include complimentary stay products, such as breakfast. However, one way to make these deals more specific would be adding or restricting a stay product based on the space type booked by the customer. This could create a great incentive for customers to choose higher categories as a result. For example, properties may want to restrict breakfast for only the lowest space category while including it for all others.
