Hey man, thanks for the reply and indeed, this helps a lot. Now, can you recommend a way to ask the user about their ages and the genders? i mean, i need to know the specific ages and genders of all the guests once they've done check-in and they have the room keys. my idea is to have a QR code in the room itself for them to scan it and access the bot. once they get the link, i ask them for the language and then i tell them to choose between general information or smart booking, which is the actual suggestion of internal activities of the hotel such as gym, spa, restaurant, kids area, etc. but to do that, i need to know their ages and genders separately to process that data and make the proper suggestions. Any ideas? Woould you like me to share what i've done so far? Thanks!
