I read in the cabana rentals online that you can also rent an umbrella with two lounge chairs on an island near Roa Rapids but I'd rather not do that if I have a decent chance of finding these chairs on my own. Are there umbrellas w/ lounge chairs near the kiddie cove and wave pool area? If I enter at opening and head straight to the back, can I find chairs with umbrellas? Any help on this would be appreciated. I'm planning on going on a weekday in mid-April and I'm thinking that it'll be crowded so I'd like a plan when going in. I'll send my husband to the lockers while I go for seats with the kids (ages 5 & 8), right?
