I've been to special/international conventions before. They are NOT lame. They are for the JW "elite." I liken them to coorporate retreats. Thanks why only big shots "pioneers, elders, MS and publishers 20+ years in "good standing" are allowed to attend. Your average R&F is not allowed. This is what really led me to wake up. I got to go to less wealthy countries and get awesome food prepared by the local friends. Non stop eating at bethel, kingdom halls and assembly halls. Entertainment by local talented friends. Gift bags. Everything. The only lame part were the tours because the guides were not professionals. "Field service" is a joke. You go out for one hour then meet back for more food, entertainment and "experiences" at the KH.
Its cool to do this in another country, but there is positively no appeal to do this if you already live in the United States. I'm sure the foreigners will love it though.
