How strict are they at the Poly with pool use from outside guests? We stayed at the BC on our last two trips and they require wrist bands and have lifeguards checking. We went to the Poly for dinner and walked down to the beach/pool area before and a lifeguard asked us to not sit at the tables, they were for resort guests. I don't mind this idea since the pool does get very crowded. Just curious to know if they are doing bands and/or checking when you go to the pool. Thanks!!
We were there March 3-10 and wristbands were not in use at all. The only trip we've seen them used were last year, late March. This trip the Volcano Pool slide was closed almost the entire time, reopening in the afternoon on the 9th. The pools were not crowded at all.
Unfortunately,it's almost everywhere you go, even at Disney... From reading through the thread, sounds like you ended up with a magical vacation all in all... ( Even though it kind of sounded like maybe you wanted to "help" them to their bus...
)
But as a PP stated at least you will be able to send your Grandson home when you've gotten your fill! That's one of my favorite things with nieces and nephews!!!


I can just say "here ya go he's poopy!"
a whole lot of people either have reservations at Ohana or the luau and just hang around to watch Wishes on the beach. In my opinion the poly beach is the best place to watch it. Head on view, not being elbowed by the mass crowds, no camping out for an hour or more to get a good spot to see wishes, no fighting over getting on the monorail or bus, and so much more that you don't have to deal with, so I don't blame them for coming to experience wishes on the Poly beach. However they should be respectful of the Cast Members, guests, and the resort because if it does become a bigger problem than it already is, they will start chasing them off. Walt knew what he was doing when he built the poly right across the lagoon! He just didn't know that society would change so terribly. 
He knows now that you will be hooked on Poly and be back. Glad you had a wonderful stay.
Now go feed Tina!!
