Hi all, I'm trying to work out how to visit the zoo with my daughter on our upcoming trip and I have an idea but would like some opinions on whether or not it is possible. To avoid going to the zoo on a weekend (assuming this is the busiest time so wanting to avoid it) my plan is to go to the zoo on the Monday morning before our flight to Hanoi which leaves Changi at 15:50. Plan is to leave the zoo by 12:30 and to get a taxi to and from the zoo. I know this isn't ideal however 4 hours is better than nothing. Also would the lockers at the zoo secure and suitable for storing our luggage? Any other advice is welcome. TIA.
