This week, I loaded an app created by Holland America Line on my phone. I may have loaded and deleted HAL's Navigator a few years ago. Yet, it's pretty apparent they've continued working on it and making improvements.
Now it's easy to keep track of a specific upcoming cruise as it provides quick and easy access to data such as boarding passes. When onboard, informational data such as daily menus are accessible. We could chat with others if we were travelling with other folks.
The app maintains a record of all prior cruises. More importantly, it also shows all future reservations. Today, we added a short one for Jay's birthday in September.
