Hello and welcome! Please read external links#what not to link to. You will see that booking services are specifically mentioned as a thing we don't link on this site. Sorry; I know you were probably just trying to help, and I hope this doesn't discourage you from continuing to add useful content, most of which is likely to be within Wikivoyage guidelines.
Have a look at the Manual of Style and linked pages at your leisure.
All the best,
