Hi, thanks for following along
As far as the pools went for the kids, Ella of course only being a year old couldn't use anything other than the splash area. Both our sea days were too cool for her to be "out of the water" in the spash area so she didn't get any water action until our last day in Ensenada when the weather cleared and it got warm out. She did like the splash area, and Jacob played there with her for a bit too, he still thought it was fun at 4yrs old.
Jacob of course wanted to try out the other pools too though. So Ella just hung out with us as we watched Jacob do slide after slide on the Mickey slide, and he also stepped a foot in the ears of the mickey pool a couple times, but it was mostly the slide for him. Then a couple of evenings he went into the Goofy pool with his grandma, or with Dh and I while grandma watched a sleeping Ella in the room. Had we not had anyone else with us to watch Ella, or to take Jacob into the Goofy pool, DH and I would have had to take turns watching Ella/swimming with Jake. With grandma there, we were also able to leave BOTH kids with her after the Goofy pool closed while DH and I went to the adults only pool/hot tub.
And for the kids club, Jacob absolutely LOVED them! We'd always drop him off in the Oceanears Club, but sometimes when we'd pick him up he'd be over in the Lab. (He would ask to go to the lab and a CM would take him, and any other children who wanted to go, over there through a special walkway).
Ella was allowed to be in the club/lab as long as an adult was with her. We'd both get visitor stickers and could come and go as we liked. Because of her size though she ended up getting knocked over by some little boys and face planted into the floor. Ended up with a bruise on her head

So if you do take your little one in, try to keep them out of the center of the mayhem, lol. There was a cute area just behind the CM's desk that had a smaller slide, perfect for toddlers and Ella loved it! She'd go on it over and over again!
Hope that helps
I will have another update up soon. I got a Mac today and so I'm just in the middle of switching over to it and then I'll get some more pics uploaded and another installment up here

Thanks for being patient
