Indiana Jones: Temple of the Forbidden Eye: The Indiana Jones building itself is really well done. The exterior looks like an actual temple and the queue leads you straight into the building.
When the ride first opened in 1995, little decoder cards were handed out so you could read the messages on the wall. My ever-so-serious dad totally scared me (and I'm pretty sure the family next in line) when I started to take a drink of water and he shouted "Wait! It says poison!" ;)
Star Tours: The line for Star Tours has always had tons of fun things to look at, such as talking robots, C-3PO, and a Star Tours pod. After the ride renovation in 2011, it's only gotten more interactive.

Haunted Mansion: This classic ride is a beauty to look at. The mansion has so much detail from the iron gates at the entrance to the little graveyard on the lawn. The ride "starts" even before you get into the doom buggies. The queue is totally interactive- from the portrait gallery to the long hall.
