How do I choose between the Blue Thunder and 18' Tropical water slides?

Both are water slides, but they're built for slightly different yards and group sizes. The Blue Thunder Water Slide is the more compact of the two at 25' long by 13' wide, and it's priced at $450/day — a good fit for a typical residential backyard and a smaller group of kids.

The 18' Tropical Dual-Lane Water Slide is bigger, with two racing lanes side by side and a larger splash pool, at $499/day. Its footprint is closer to 35' long, so it needs a more generous setup area, but the dual lanes mean two kids can race down at once instead of taking turns — a real plus for a bigger group or an all-day summer event.

If your yard is on the smaller side or your group is modest, Blue Thunder is the easier fit. If you've got the space and want the extra racing element, the Tropical Dual-Lane is worth the larger footprint.
