Washing prior to kiddush on Sukkos

Should one wash before Kiddush on sukkos to avoid leaving the sukkah after making the bracha of leshev basukkah?

There is a problem of shinuy makom when leaving the succah after Kiddush, before Hamotzie. The solution recommended by the Rav is for all members except the baal habayit to wash before entering the Succah. The Baal Habayit himself should wash in the Succah after Kiddush.
