1. Octopus Cards are your best friends
If you're travelling in Hong Kong for a few days where you would be using public transport regularly, I would definitely recommend you to nip to the closest MTR station service desk to buy one of these nifty cards. To use this card, there would be a sum of money which would be deducted with every purchase from public transports (except taxis), stores and restaurants. To top the octopus card up, you can go to any convenience store like Seven Eleven and Circle K where you can ask for a top up.When you purchase the card, you would need to pay a deposit and upon return, there would be a refund a sum of money.
2. Tissues, tissues, tissues
Did I stress that you need tissues enough? Some of you may not know the importance of having a packet of tissues or a napkin from the meal that you had yesterday. Unless you are going to the toilet in large shopping centres, be prepared to use your own precious stash of tissues. So always bring some tissue with you to the toilet regardless because we don't want emergencies like pleadingly asking for anyone to pass you some tissues. If you want to be extra fancy and try something new, Tempo Tissues are scented with a variety of flavours from mint to peach.
