Not very sure about my itinery as it is my 1st time. Going with grandfather who tires easily. Am arriving at HK around 10.30 a.m. and staying at Royal Plaza Hotel. Is this itinery too much?

Day 1: Arrive at hotel then Victoria Peak and then Symphony of lights (will there be too much walking? what is the easiest way?)
Day 2: Big Buddha and Citygate Outlet
Day 3: Dried Seafood Street (Des Voeux Road West), TST, Night markets
Day 4: Wong Tai Sin temple and last minute shopping
