Any hotels you are working with would like to offer discounts or promotions. Or, maybe you can partner with a travel agency or agent and members can easily book hotels in the areas you'll be traveling to.
At the risk of boring some of the readers, I would like to update my previous comment. On my casino visit last weekend, I was able to surpass my own record. With an average bet size of $5 per spin, the total amount of substantial payouts was again about $6,000 (including one handpay). However, this time my wife and I came out ahead by $2,400. So the effectiveness was 40%.
As I mentioned earlier, it's very difficult to reach such a high percentage. Of course there are some exceptions where a much higher percentage can be achieved, such as winning the progressive Grand. One such example can be found on another thread in this section by Refzz entitled "A Christmas Miracle" and dated Dec. 27, 2017. Another example is by Slot Shark Dan ("Eureka Lock It Link GRAND" on July 4, 2018).
