So, you have almost 4 days to see the cities. You can do a lot of things. I have some one day tour suggestions, you can follow anyday you want. Disneyland for one day if you would like to see this places in the first day. If not, you can see the Big Buddha by Nging Ping 360 first and then get to Disneyland. One day to Ocean Park, SOHO nearby Central which is food zone. Another day to Repulse Bay, Victoria Peak, Wax Museum, Avenue of Stars and Light of Symphony show at night. Last day to shopping in Tsim Sha Tsui, Mongkok, Temple Street night market. If you want agents, you can try to contact Travelchinaguide. My friend joined it. It seems not bad.
