How to add option "Add to favourites"?

I’m implementing a website that presents some information about hotels.
There is no option to reserve or book a room or anything like that.
This is only informational.
I want to give customers option to make a list of favourite hotels.
For example - I’m on the hotel x page and I want to click “add to favourite list” or “add to wish list”.
I’m on the hotel Y page and I click again “add to wishlist”.
At the end I can review my favourite list.
That’s all.
