Hi Desa1969, if you are following some of the musical acts for entertainment, basically divided into 2 zones. The Padang zone 4 and Village zone 1. So, you have to check what acts are playing in which zone. Both zones are quite a walking distance apart, so you need to camp in one zone so as to not miss. Besides, Padang Zone 4 has several sharp turns, which means the drivers will slow down real fast and you can catch glimpse of the cars as they passed. While Village Zone 1 is where the winning paddock is. So cannot really recommend any particular zones unless you really know what you want. Remember, both zones require you to pay a different price. So you need to book different tickets. Best suggestion is to book different zones for different day, so you can have a day in each zone to taste the action.

The drivers were staying at the Ritz Carlton in Singapore

You can choose your seats from the official F1 website

Yes you can as long you don't block others. I normally take pictures of cars during practices and qualify but not during the race so you can watch it properly.

no free wifi but with passport buy singtel sim its small dollar for 100gB data only probably less than $15 us it was cheap sold every place

Lucky you! You will be surrounded by big screens which give you all the race facts. Have a great race!
