Greg trying to prevent Dharma from doing what she wanted was stupid. He should know by now that she is a free spirit, and he can not dictate what she can and can not do. It was good that he ended up compromising, rather than forbidding her to go.
The close-up shots in the van were a nice touch; I really felt like I was in the crowded van with them.
Greg being ridiculously nitpicky was typical. He is so unbelievably annoying!
Larry working as a night security guard was mildly amusing, but the plot could have been funnier.
