Questions hoteliers ask
See every questionSet the journey up once and it runs. Confirmation, pre-arrival, in-stay and post-stay messages go out on time to the guests they apply to, without anyone having to remember. What each guest gets depends on their room, their stay and what they booked.
Yes. One message reaches every guest currently in house, which is what you need for a closed pool, a lift out of service or an event on tonight. It goes out on the channel each guest already uses, in the language they booked in.
Whichever language the traveller wrote in. Your team doesn't need to speak it, and you don't need a separate inbox for each market you sell to. The whole thread stays in one place, so whoever picks it up next can see everything that was said.
Yes. Routine questions get answered the moment they arrive, drawn from the details your hotel has already written down. Anything needing judgement is handed to your team with the whole conversation attached, so nobody starts from a blank screen or asks the traveller to repeat themselves.
Yes. WhatsApp, email, webchat, calls and the threads coming through your PMS all arrive in the same inbox, grouped by traveller rather than by channel. Someone who asks on webchat and follows up on WhatsApp is one conversation, not two separate ones.
