DH, 8 month old DS and I have a 12 hour stopover in Singapore airport while we wait for flight to Australia. We have booked the transit hotel and will pay on credit card but I have no idea how much cash we might need while we are there. We are there between 8am and 8pm so will definately need to buy a couple of meals (although will have food for DS with us already) and we are not planning on going on a spending spree so what do you think? Would £50 be enough?
