I’d be happy to attend an EF Mass but there are none offered in the dioceses where I was travelling so those sites are not of much good.
As for
Masstimes.org, of the three dioceses I travelled through, only 3 parishes were listed and none had Mass times.
It’s been several years since I’ve seen hotels/motels include Mass times or even a listing of churches in the directory they put in the rooms.
I travel quite a bit, so I understand looking for Mass times and such. When
Masstimes.org doesn’t meet my needs, I Google it. I can get just as easily get to the diocesan website or the parish websites of the city I’m traveling to. If they don’t have a webpage or a bulletin online, a simple phone call is all it takes. Many parishes even have answering machines so that when you call, it gives out the Mass times.
Many of the hotels I stay at (which would be 3 to 5 stars) do have a handbook that includes at the very least, nearby Catholic parishes as well as others. This includes casino hotels, believe it or not.
With all the tools at hand, there is no reason not to know at the least, what the Catholic Church in town is, if not the times, achieved with a simple phone call. Since we are already on the internet, it isn’t that much work to find it on Google.
I do have a funny quick story; I was in a town and thought I knew where I was going (I was plenty early). I drove through the small town (Grants) and didn’t see the Church where I thought it was, but I was probably looking in the wrong direction. Nonetheless, I pulled into a parking lot to turn around, and spotted some people putting their store purchases in the trunk. I asked them nicely if they knew were the Catholic Church was. The two men said they were going in that direction and to follow them; they drove me right to it and were very nice.
What was the parking lot? Liquor store parking lot.

And I was a single traveler, a woman alone in an expensive (rental) car (not by my choosing, but LOVED it!). God was looking out for me, for sure. Pretty cool.
