My DD11 is into slides too so I can share what we found out. We stayed at POR and visited many of the resorts to check their Xmas decorations AND their pools and slides, to see where should we stay in future trips. I'll talk mainly about the slides.
She loved the POR one as it turns 4 times (2 S in a row). POFQ has a pretty slide with a dragon but the slide is just like an L, not too long. Fine for younger children. POR Ol' man island beats it hands down.
She was most impressed by the Luna Park one at the Boardwalk. It's shaped like a rollercoaster and it's 200 ft. long. The longest anywhere with several circles.
- SAB at BC/YC is huge, very pretty, the slide is over 50 ft. long a straight drop from VERY high.
- CR has an old style pool but they put a nice slide there, she gave it a thumbs up.
- WL very short slide.
- AKL longer than WL but nothing wow. Just ok.
- GF couldn't find the slide (that doesn't mean they don't have it. We went at night and it was freezing so we look a little and gave up.)
- Didn't have time to check Poly
- CSR has a long slide. I believe is around 160 ft. or something like that BUT she didn't like it as it was mostly straight. Just a couple of turns. It's cute as it has a jaguar or leopard toward the middle that gets you wet while in the slide. POR has something similar. She preferred PORs.
-CBR didn't go there
All the values do NOT have slides.
This is all from LOOKING at them, not trying them. Only tried POR.
Hope this helps
