Extras that sell, without anyone asking
Breakfast, parking, late check-out and experiences offered at the moment a guest is most likely to say yes, and booked straight into the PMS.
Group Lumen is our demo group: six hotels, each in its own brand and language.
What it does, exactly
Automated upsells offer each hotel's extras to guests before and during their stay, on WhatsApp, email and the guest app. Offers are timed and matched to the booking, and every order lands in the PMS as an extra on the reservation. At C-Hotels Silt that came to more than €24,000 in the first three months.

Questions hoteliers ask
See every questionBy offering at the moment a guest is most likely to say yes, in the channel they're already using. Late checkout the night before, breakfast before arrival, an upgrade while they're still deciding. The offer goes out on its own and the answer comes back in the same thread.
No. Offers go out through your own channels rather than through an OTA, so what a guest spends on an upgrade or a late checkout stays with you. There's no per-transaction cut and no third party sitting between you and your own guest.
Whatever you already offer: breakfast, room upgrades, early check-in, late checkout, transfers, experiences and anything else on your list. If your team sells it at the desk today, it can be offered ahead of time in the channel the guest is already using.
Not if the timing is right and the offer applies to them. Guests only get offers relevant to their room and their stay, and anyone who has already bought something isn't offered it again. An upgrade offered while someone is still deciding reads as service.
