Staying at the Marriott which charges for WiFi. So I'm hoping to hear more about that area.
The Marriott gives free wifi if you sign up for their Marriott rewards program before booking. You might be able to sign up and attach it to your booking after the fact and still get the free wifi.
You also get discounted rates on the rooms. Try logging into your account and switching to their member rate for the same room. It's stupid they do this, but since it's free to become a member, you may as well take advantage of it.
For a booking I have in Peru, they kept dropping the price over the course of a month or 2. I just kept changing my room and selecting the exact same one again to get the lower price. Saved a few hundred dollars.
