During the first night at the International Inn, Dep. Wiegle shows Lt Dangle her sunburn, patterned around a bathing suit and a bra. The next day she appears on the beach with Dep. Johnson wearing the bathing suit/bra combination, but without the burn. It would appear these two scenes were originally shot to appear in reverse order.
At the end of the movie when Terry comes around the bus on roller skates playing a ukulele, you can see the smoke stacks of the RMS Queen Mary (a museum/hotel in Long Beach, CA) reflected in the bus windows.
