I believe that a lot of visitors to the RGV cancelled during the summer when the price of fuel was staggering. (I know of several friends that did just that.) Now, that it has come down, they have made other plans.
Also possible that some have been hit so hard by all this economic downturn that they have no means to get to the RGV.
It is early in the season, maybe some of them will change their minds as the cold weather sets in, that will make an impression on those of us in the colder climes??
It surely is a different world than just 12 months ago, eh?? SIGH
