We have pretty good speed for our WiFi here, so it is a selling point. I have had a few guests who used it to work remotely. The tool that Air is pushing does not seem to be available to us. I posted a photo of my laptop on a popular speed test site. The people who know about such things know that is only what was available at the time the photo was taken. The rest will be fine, it is pretty fast all the time.
I am not wanting to push a lot of amenities, either. We have some big downsides here, and if guests find a nice feature they appreciate, there will be better reviews.
