zhuzhu - initially during briefing i did ask cos i saw on e info paper they gave us is 50% of adult tips.
but e lady there said no need cos belle too small to understand wat is doing on.
but when check in time, i asked e tour leader (from sin agency), she said need pay 50% of adult tip but i told her during briefing e lady said no need etc. then she said 'sui yi/ up to you.
but later during e trip, e tour leader, tour guide n e driver treated belle very well... e tour leader even bought her biscuits, icecream wafe, chocolate etc... also belle should not ve any meals but most time she is given a set too at no charges.
so in e end looking at e overall services, we gave more cos e tour guide made us enjoyed this trip from start to finish. He is very very attentive n extremely humorous!!!
