I just bought Wii Sports Resort (inc Motion plus) and also bought an additional Motion Plus for the two player games.
When Motion Plus is fitted the + and Home keys don't work on one of my remotes (the remote works perfectly on other games with no Motion Plus). This means I can't pause the game to recalibrate the motion plus or exit to the Wii menu (so I have to switch the power off to get out of the game).
I tried the faulty(?) remote with both Motion Plus units and get the same problem. My other remote works fine with both Motion Plus units.
Has anyone else had this problem? If so were you able to fix it?
