Question about GOG purchases

I want to buy Divine Divinity to play while on vacation. I'm using her laptop right now and was wondering if I buy it and download it on this laptop, can I redownload it on my computer as well when I get back to my desktop?

Yup, the game is added to your online account with them, you can redownload the game all you want.

Yep, when you buy a game from GOG it's yours to do what you want with it. Imagine that! You buy something and you actually own it.
