A few threads on this ...below. A relative of mine recently went to Canada & he reckoned the hotel was 30% higher than he would have paid via Expedia etc and no reward points and the cost of the tours are grossly inflated , especially as the Society don't pay the ( usually ) pioneer guides. Because a show is put on for the "delegates" and everybody is ( superficially ) super friendly , they kind of are guilt tripped into donating far more than what they should. My relative put £300 donation on his credit card ( for him & his wife ) at the convention so goodness knows how much the whole convention got in cash.
Even back in 2009 , 6 days in France from the USA was $2900 plus $500 airline tax. This did include breakfast & lunch but not dinner , drinks , tips , "donations" etc etc. You could probably double that cost nowadays.

" A friend of mine was a delegate to an international convention a few years back and he said the price he paid through the WT society was almost double what he could have arranged independently for flights, hotels and tours. The thought was that the extra money was used to fund a CO and his wife who became the ‘Group Captain’ even though my friend said he really did nothing of any worth except drink a lot of red wine. "
"A friend of mine went to a international convention in Africa 20 years ago and he was telling me that the travel company used was a JW operation that charged more than double the price of what he could have arranged independently. But the delegates had to be approved by local elders as suitable candidates and no independent travel was allowed. "
