Home Depot (or maybe it was Lowe's... any DIY store) had 1/2" thick chipboard in 2'x4' sheets. That would be perfect - easy to carry and store, two next to each other make a perfect 4'x4' board. I didn't want them shifting during game play, so I inserted some leftover Ikea furniture dowels into one side, and corresponding holes into the other half of the board to keep things together during the game.

Since this was going on top of the breakfast table, which is a bar-height piece of furniture my wife is WAY more fond of than she is of game tables, I helped out by outfitting the bottom of the sections with padded feet so that they would not damage any surface they are put on. These self-adhesive, padded feet are sold for people who want to easily move their heavy furniture around hardwood floors, and are found at any hardware store or Target/WalMart-type store.
To finish the playing surface, I chose a time-efficient and aesthetically pleasing Easy Button - Rust-oleum Textured Spray Paint, Deep Forest.

Combined with the Jungle Buildings and Jungle Plants, the table is a great start to infinite Infinity adventures on Paradiso.
