Very nice country. Clean and Discipline people that includes the tourist (or you pay the corresponding fine). A lot of theme park for the entire family or for couples. Different hotels from average to 5 star. Cab driver are nice and very accomodating.
I'm visiting Singapore early next year. Is there anything you can suggest I should see, do or try to eat?
I would say bring your light clothes as Singapore is known for its humid weather. It takes about a few days to tour around the city/attraction places. Shopping malls are everywhere. Hopefully to see you here when your visiting the city.
Is it safe to visit and travel Singapore for 2 girls together without any family member or any boys?
If you visit Singapore and would like to buy some gift, you may get it at Kampoong Bugis, Chinatown or in Mustafa Center. Except in Mustafa Center, you may bargain the price. So you can save your money :) Unless you have a lot of money to spend :D .
If your traveling to Singapore regardless the time of year; always ensure you pick yourself up a MRT (which stands for "Mass Rapid Transport" this is their local monorail train system) card at the airport. This card will allow you catch the train and buses throughout Singapore. They have a tourist MRT card which is about $10.00 to purchase the cool thing about it, is that once you have it you can top it up anytime throughout your trip and when your leaving Singapore, you can return it...
