Your booking experience is generally pretty good but there's one huge security concern you need to address. You email the passwords in plain text, the implication being that you also store the passwords in plain text. Best case, this means emails can be intercepted and passwords stolen, and worst case if you get hacked you would have compromised the passwords of all your users. If people only used a new password for your website, this wouldn't be so bad but users nearly always re-use passwords on other websites. Sorry for the doomsday speech. Best Regards, Tim
