Sukkot will be observed by all the nations in the times of the Messiah.
Agudath Israel and Chabad are two organizations whose members do not engage in ecumenical exercises. Chabad, of course, is a pioneer at publicizing the Sheva Mitzvot B’nai Noach, but now almost everyone Orthodox is on that bandwagon.

I'm willing to believe that Agudat Yisra'el doesn't engage in ecumenicism, but I'm not so sure about CHaBa"D, if for no other reason than they are so prominent, especially in encouraging public celebrations of Chanukkah (which is a good thing when it isn't misunderstood).
Unfortunately, the Chief Rabbinate of Israel has been a disgrace in its ecumenical activities, as have the Jews of Rome (where the Pope might as well be a member of the congregation). And of course, "Modern Orthodoxy" is the absolute worst of all (discounting heretical "branches" completely, of course).
