At the end of the episode where Kate is staring out the window, she has a flashback of when Angel bit her and told her to "stay down or they will kill her". The bite mark from Angel is more underneath her ear, when it goes back to her staring out the window it is closer to her jugular (almost under her chin)
At the end, Cordelia makes a remark about having returned everything she'd stolen. However, the necklace that she was wearing at the time was the same exact necklace she had stolen off the mannequin earlier at the museum.
Wesley says Angel drank human blood from a living person, which is something he hasn't done in a very long time. He drank Buffy's blood a year and a half ago. Buffy the Vampire Slayer 3x22 "Graduation Day".
After Angel, Gunn, Menlo and Vyasa blow the vault, there is a close up shot of the destroyed lock mechanism. You can clearly see that it is made out of fiberboard or some kind of particle board, not metal.
A bus trip from Las Vegas to Los Angeles takes about five and a half hours. If Jay-Don's bus arrives at midnight, it had to have departed around half past six, which means the vampire would have had to get on the bus while the sun was still up.
Incorrect goof. The sun sets around 4:30PM in Las Vegas during the winter months when this was filmed.

The heavy 1-tonne sarcophagus was definitely not schlepped into the basement by museum employees or delivery people. There's bound to be some kind of dolly around, or in any case the basement needs to be dolly-accessible and they could have brought their own. The only reason they don't is to further the plot, because with a dolly, at most two people would have needed to go in.
