This is just how hotels make money. The key is to be very nice to the person who actually brings out the flipchart and asked for it on site. Then it’s on them to actually record that they did it and you know what people are lazy enough and failed to record it.

Thanks for the tip, I'll try it next time! I mean even if I had to tip a $20 I'd still be saving a few hundred

Next time, just ship it from Walmart or Amazon and throw it away when done with it.
