It depends. Do you want a nicer pool or will you really be swimming? Will you basically just be using your room to sleep in? Are you on a tight budget?
We stayed at Pop recently and really enjoyed it. It was me, my 4yo, and my sister. If you bring tons of luggage it might be a tight fit. I had enough room for our things without a problem, but we didn't overpack for the most part.
It was tight in the room, but I was able to keep my stroller open (it was hard to roll it into the room, though, since there isn't much space between the open door and the bed). We were out of the room all day long and didn't return until after the parks closed at night (7pm closing at most parks). We would get back to the room, get ice for the cooler, repack our bag for the next day, eat dinner if we hadn't already, watch a little tv, and go to sleep. Not worth paying the extra $ for that.My son played in the pop jets one day, but we didn't use the pool at all so that didn't matter.
Really just depends on what you want and your budget.
