You can hang out at the Sandbox Restaurant, Wish Willies Restaurant & Bar, Oceanside Restaurant & Bar, Popeye's Restaurant & Bar and on Thursdays - Saturday nights you can go to the Sunset View Disco till 3:00 AM..... All within walking distance.
Usually people dine at the restaurant of their choice first, meet new friends and then head out for Karaoki &/or dancing afterwards....
The docks are usually nice places to hang out and count the stars, feel the fresh breeze in your face and chat, getting to know other travellers..
Have fun!
