is 1 day enough for the visit to Macau?

Two nights in Macao is totally enough to cover all the attractions there. I stayed there for 2D1N and had a good time! Well don't miss the Fisherman Wharf, Senado Square, Ruins of St. Pauls and Monte Fort, Macao Museum, A-ma Temple and Macao Tower. If you are interested, go to to the Casino for fun.

I just heard that the Superstar Virgo Cruise is worthwhile. U'd better search for more info about that!

Thanks a lot Anish for all your help.
If you don't mind me asking, can you please guide me about sightseeing in Shenzhen and if any visa that i would have to take?

Also can you suggest a good place to stay in Hong Kong & Macao.

Thanks in advance!!!

Well, to tour Shenzhen, you have to apply for a Chinese visa in advance. U should not miss the Window of the World, Splendid China and Folk Cultural Village, Safari Park and Dameisha or Xiaomeisha (beach resort). For shopping, the Dongmen Laojie pedestrian is recommmended.

If ur want budget accommodation, I suggest you find a suitable one near Tsim Sha Tsui in HK. Well, the accommodation fare in Macao is usually high. I just know a cheap one named San Va Hospedaria.
