I will disagree with you on this one.
Disney has always welcomed others to their resort activities; such as Chip & Dale Campfire, WL Ladybug release and architecture tour, Grand Floridian Prince/cess Promenade, wide range of entertainment and animal programs at AKL, Polynesian Hula Dancing ............ and on and on. The hotels have always welcomed guests from other Disney hotels and those just visiting the hotel to look or eat to participate. We have participated in many over the years and never was there so many folks participating that it was an issue. And there is a wide number of fee based activites, they welcome money from anyone who wishes to pay.
I can't find this restriction printed on any activities sheet. Can you show us one of the calendars that says it is restricted, because that would help many that were not told this by Disney CMs.
"Free soda" .......... if you mean refillable mugs, then they are welcome at all Disney resorts, not just your own unless they have recently changed that rule. This way if you go eat at another resort you may take your mug. The chip in the mug determines if you get soda. There is no longer any free soda since the chip cups were introduced years ago (other than in parks where folks rip Disney off).
Agree, pools other than sister resorts and DVC rules, are off limits except for guests.
