secondary authentication WiFi is a plague for all of my non-smart devices. Even my phone sometimes forgets to popup the hotel authentication screen. A hack I use on my phone (and laptops) is visit http://captive.apple.com this is Apple's site that will sort of trigger a prompt if you're on a Mac / iPhone / iPad and haven't seen the hotel pop-up yet. It works every time (it just says success if you're already online) I'm honestly not surprised this didn't work on the Tomtom. I doubt Garmin would fair much better. Also, having not called our support in a few years, I'm glad to hear it's still helpful. I hope things get going for you soon.
