When you are dealing with multiple locations you need to keep things simple; or as the saying goes, keep it simple stupid or 'kiss'.
This production of Hamlet uses kids from 10-15 years old and when designing scene changes they must be quick and easy. Remember, kids have a lot to do. First they must memorize a script and remember folks this is Hamlet we are talking about. Then they go through the blocking process, memorizing where to stand at a given time, change into costumes and then.....change the set. It's a lot to do, even for an adult!
On some shows I eliminated the scene changes all together, one was Les Miserables. We did not have a turn table and I went back to the 'kiss' method so the audience could focus on the show and not the scene changes.
Also remember sometimes your playing space will dictate if you can accommodate a change or not. I have designed in many spaces where wing space was not given.
So if you feel over whelmed in any design situation remember to keep it simple.
Enjoy reading my encounters in and around theatre set design.
