"check-in when our guest check-in via diefferent credit cards?" - Maybe the Cloud would generate a userkey for your user profile and when you want to log in you will be asked for it and the credit card number. If you now have a different credit card number it would be only added to the regular user profile.

"And we have to differentiate between "normal" guests and corporate guests" - The cloud would have two areas, one for "normal" guests and one for corporate guests. And when you start the app you will be ask for your reason to check in "business" or "pleasure", if you choose one, the program would adjust it self to the guest.

"How can you match person and profile?" - I'm sorry but I don't understand this question :(

Hope you understand what I mean :)

No, my idea of a application should not be similar to Facebook. It acts like a cloud where everything is interconnected. This allows easy data exchange and comfortable working. Sure, it looks like a social network, but it isn't a kind of facebook for hotels and I read your idea and it is definitely different than mine, I have also considered how the cloud would work technically, and how the guest can log on exactly, etc.

Soon there will be the english rranslation, so don't worry. Also good luck to you! :)

Thank you! I thought about this too, and I think the best solution is to let store and protect these profiles by the Deutschen Telekom, they also did a great job with thier own "Cloud"-Project. Another idea was, that in addition to the community-scouts there are also community-IT specialist who controls the access.

Thanky you very much for your love! :)

Thanks! :)

Danke für dein Feedback, du hast vermutlich Recht, ich versuche das mal beim Update umzusetzen! :)
