I simply bought two 4x8 sheets of 1/4" ply and can put those down wherever and whenever. Very light and easy to move around.

I'm considering also something where i get thicker ply and ahdering wood floor to both sides so I can have two different types of wood flooring, and I can slide the two sheets next to each other and have an 8x8 floor, flip and have another 8x8. That one will be heavy as crap though.
