We are pretty fast walkers - wondering if it will be faster to walk to the parks than take the water taxi. Also, where would we go through security? At the resort or the park entrance? Same for the taxi and walking? Thanks!
I'll also add that if you're going to Universal, the water taxi drops you off closer to that entrance. If you're walking, the path is closer to the IOA entrance. Not a huge difference in terms of distance, but it does make for a longer walk if you were walking to Universal. Personally, I'd take advantage of the water taxi to save my legs for the park.
The walk is not bad at all. we were feeling adventurous on our last stay and walked from portofino to sapphire falls. Not a bad walk at all. And sapphire falls is absolutely beautiful. We ate several times there and fell in love with the place.
