Answer 1

You can't pass in arbitrary parameters such as hot_id, room_id, etc to PayPal (or omnipay) because it won't know what to do with them. PayPal is only intended to take certain parameters and the ones that PayPal does not take are ignored by Omnipay.
You may have to provide all of these extra parameters as part of the description parameter, which PayPal does understand.
Ideally these should be displayed by your application in some kind of useful format to the user before redirecting the user to the PayPal checkout page.
