I've noticed the same. We started going around 2009 when the economy was in the toilet and things were practically free. Even as a lowly pearl, the offers were great for several years, but they don't seem as generous recently. My guess is that the economy is good now so they don't have to give away as much to lure people to town.

Or, they may have just looked at how often we visit and realized that we're now addicted and will go regardless of what it costs
