Grand Swim Resort Escape

Recently, I am planning to take my family to grand swim resort. But they are frightened to swim there. At first I have tried to swim and I enjoyed a lot. So, I went inside to take my family here. But the resort gate is closed. Now, I need to escape from here. So can you please find out the related objects and solve the puzzles to open the main door and help me to Escape from this grand swim resort as soon as possible.
