I put together an informational packet with tons of information from Frommers.com. (I wouldn't call it a brochure because it was a very plain Word document). I like Frommer's because I find the information accurate. Also, it gives more than just hotel tips, like a history of the location, restaurant recommendations, available activities, local foods, walking tours, etc. I saw lots of people reading the packets. My mom told me that they used it while sight seeing in the capital with some relatives.
I also read a threat where the bride arranged with her hotel to give each guest a coupon for a free drink. We all know a free drink coupon will be put to good use! I thought that was a great idea! If your hotel is all-inclusive, maybe you can do a free drink coupon to a local bar or a coupon for free $5 in chips at the hotel casino, or anything else that makes sense for your situation.
