When checking in guests "manually" it would be nice be be able to "force" a registration card to show up in the operator. Imagine walking to a check in desk, saying your name, and the receptionist makes your registration card appear on a tablet in front of you for you to fill in.
It would connect the "kiosk" option from hostels, with the personal service of hotels.

It would be great if guests would receive an automatic e-mail after departure to review their stay and if we could choose to show these reviews to other guests in the distributor when choosing/booking a room.

Alternatively, guest can be asked to provide review during online check-out as well.

Currently, if we set a restriction of 3 days (weekend) and guests search for a stay of 2 days the system offers the guest the next weekend where there is no restriction instead of offering/showing the restriction.
So, show the guest the restriction so they can change their stay to 3 days to book at our property.

receive notification if email cannot be delivered to guest due to wrong email adress of customer

Currently customer added email can be disabled only in GA, for all guest. If a property is using a third party integration for guest journey (for certain guests), it would create duplicate emails and guest will receive too many mails.
Would it be feasible to decide for each reservation if customer added email should be sent?

Allow clients to scan their ID or Passport from Mews Navigator to make the Online Check-In experience even better.

Give the possibility to add a small text to the confirmation and quotation emails. The best thing would be a field in the reservation module and a placeholder in the mail template... so that we are able to customize our emails a bit more...

How can we make sure that the guests receive a confirmation email for their reservation (with arrival/return date, what is included in the price and what is not included...) after having taken their reservation? And what parameter do I have to modify to achieve this functionality?

This will allow not to miss any details for any guest, from booking stage and when reviewing the reservation report.

This would be especially useful for reservations for which there is no Travel Agency involved.

We would like to have the property logo showed on the Magic Link link pages. So it will not be seen as spam due to that you only see "Mews" in the address bar.

A Report for linen change for all stayovers (day of arival +2+2+2+2 ... except changing day = departure day) is needed so housekeeping knows in which rooms the linen needs to be changed. (Accor standard)

At the moment it is not possible to set the footer of invoices in different languages.
As we thank you the guest and wish him/her a good journey it is necessary to have the possibility to set this in other languages than only our main language.

The heading (Invoice) and the names of the products are translated as well. Why not the footer?

Have the option to automatically notify the property when an email to the guest is undelivered.

The standard ''Oh no, your payment failed'' is not every hotels standard tone of voice. Also, we do not have the 24 hours policy to authorize. This should be dealt with ASAP since we have a lot of unsatisfied customers having these emails sent.

At the moment, when the Guest is making the online check-in, the email address from the OTA (not the real email address) is already populated. THe guest should be obliged to introduce his real email address.
