Hawaiian Falls or Bahama Beaches

I've not been to Bahama Beaches, but love Hawaiian Falls in The Colony. It's much nicer/newer/cleaner than the one in N. Garland.

Hawaiian hands down.

I have not been to bahama beaches, but I have been to a Hawiian Falls and we have passes to NRH2O. I would say it depends on the age of your kids. The splash pools are all (really!!) the same. If they have a river, a play area and a zero entry pool younger kids will be just as happy.
However, if you have kids who want rides, etc. Bahama beaches looks a little lack luster in that area.
However, Hawaiian Falls charges for coolers!! That ticked me off. here I am trying to save my $$, offer my kids healthy snacks from home and you are going to charge me to do so?! I have officially banned them for that reason alone.
I typically say most water parks are the same after having worked at one for almost 8 years - LOL! so take my input with a grain of salt.
Regardless, hope you have a blast!

I have been to both and would recommend Hawaii. I really didn't care for either one, but I felt much safer in Hawaii.

We went to Hawaiian falls in Roanoke yesterday and i was actually disappointed. There was not much for the kids to do besides run around in over sized sprinklers. I am not familiar with Bahama beaches, but I do know that Hurricane Harbor and NrH2o are way better. HTH!

Never been to the Bahamas, but going once again to Hawaii this summer. My vote would be Hawaii. Soooo beautiful there, clean, etc. and safe. I always have my guard just up a bit more when I'm in another country.

These are water parks? I think most people are guessing you are talking about an actual vacation.
