Dolphin Balloons Where Should I Go On Holiday?

Where should i go on holiday? - dolphin balloons

I'm 16 and I'm planning a summer vacation for my mother, my father, my best friend and me. I choose to do the goal, booking flights, accommodation and things while we are there. My mother told me she wanted to spend a holiday by the sea, maybe somewhere in Spain. Can someone help me? I want a place near the theme parks, zoos or marine parks, and of course the beach. I would like to swim with dolphins, scuba dive or go ballooning or something fun like that!
