The plotline centering on Garrett's Farm deviates significantly from the source book. Booth actually didn't disclose his true identity but used the Boyd alias. There were several Garrett family members at the house (not just a voluptuous daughter), and they welcomed "Boyd," thinking he was an injured Confederate soldier. He slept in their house for two nights. One of the Garretts eventually became suspicious of his and Herold's intentions, thinking they were going to steal the Garretts' horses in the middle of the night to make a getaway, and this is why they were locked in the barn that fateful night.
