It is easy to install and it is very easy to use. It is very easy to share the LUCID Messenger with the guests. I liked that I can send messages to the guest and they will be received on the guest phone. It is very easy to get the SMS messages sent to the guest from the manager. I liked that I could send group SMS to the guests. I think that I can send the SMS to the guests in different languages. I can't send SMS to the guests who do not have the LUCID Messenger. It has helped us to communicate with the guests.
