What is best Waterpark for Memorial weekend Saturday?

[Palenque]

We are going to Universal Monday - Friday with a 5 day pass and want to do a water park on our last day which is Saturday 28 May on memorial day weekend.

I know the waterparks are going to be be crowded , but what would be the best park for handing the crowds and lines? Also we have 2 seven year old children.

We have two plus features left on some Disney passes so we could do Blizzard Beach or Typhoon Lagoon for free.

But how would Wet N Wild or Water Mania (never been to either) be for the
line /crowd issue?

Any suggestions would be appreciated.

They are all going to be crowded and reach capacity quickly if the weather is nice. Just get there early, be part of the crowd waiting when they open. Then ride the rides before the lines get too long. It will be that way at all 3 parks.

Are there chairs and shade at Blizzard beach's wave pool?
What of relaxing places to soak your feet and veg?
Any Palm trees?

I think typhoon lagoon is the best waterpark period

There are chairs and shade at both water parks. I would get there early for the shade areas.
