Hide personal information and grab from user account

Just wondering if it is possible to hide the name, email, and other personal information and grab them from the user registration information. the planned website will be for registered users only and it would make more sense to add all bookings under the logged in user name in order to also have a history of their bookings somehow!

Yes, just the name and id of these fields must be there. You can delete the tag and enter your own html form element. The hard part will be to get it filled with the informations. For that you will need to write a script.
