Runway usage is primarily based on wind direction. That means that, if the wind is blowing in a different direction, they may be landing aircraft in a different direction.
My advice would be to keep an eye out while you are on your way to the airport and try to spot some aircraft to see which direction they are landing in. Chances are, if the weather is not unstable or stormy, they will continue to land in this direction for a while. This will tell you if it's worth while going straight to the Wendy's location.
The good news is that there are a few different options if they are not landing in this direction. Have a look at my spotting tips map before you head out just in case the Wendy's location doesn't work out for you. You can still enjoy a great spotting trip, even at a different location.
Good luck, and happy spotting!
