It is great to see you that you are enjoying yoir anniversary and you got the perfect hotel that suits your liking and the warm reception is also top notch. Even though it doesn't take the management anything to put such writing up to welcome you. It is cool as they deem it fit to do to acknowledge your anniversary.
It is annoying when you need to use network and its fail i have been in the shoe too. However, for the fact that you can still operate on your phone sounds cool. I do hope you enjoy your holiday and anniversary.
