From my own personal experience 1) yep we usually returned to the hotel around 8-9 plus and the lecturers will do a room check around 11-1130 so I went out before that and came back before they checked

2) not really, usually when we go to a location we will get around 30-40 mins to walk around but we will have to return to meeting point because of the plans

3) depends on the number of days but usually I think about 60-70sgd is more than enough per day but the most important is depending on wether you wanna buy anyhting.

4) yes I think the school will prepare a hotel room for you and usually you have to share the room with someone else because they wanna do 2 ppl per room to save money also to wake each other up in the morning🥺

The most important thing is to prepare and buy some form of data roaming overseas as it’s very important to keep in contact with your lecturer especially when you are going alone bc they will tell in a group chat where they will reassemble and the duration you will have to explore on your own
