I'm sure that the resorts look at opening their pool to non-guests as a way to do a little pr and maybe encourage people to stay at their resort on future visits to Disney. I don't really see what the big deal is. All the hotels we are discussing are owned by the same company, so all the money is going in the same pocket. If you have been given permission by a CM, it would stand to reason that there is enough room for everybody at the pool.
