Anton:
No one brings their own beach umbrella-it's too windy-you'll be chasing it all day. The Hyatt is great-I've stayed there 3 times and will be going again at the end of July-can't wait! Restaurants are great, staff is awesome, chairs easily available but you may want to take turns getting up early to get a hut-too hot to sit in the full sun. You can always nap on the beach later on...

Enjoy!!!
