Good afternoon Julie,
Thanks for getting in touch, to date there are 5 fellow travellers stopping over in Singapore prior to the main tour starting, all are female with ages ranging from 41 to 69. To date there are 12 travellers, (17 travellers in total) on the main tour, ages range from 37 to 79 with a near enough 50/50 male to female split.
I hope this helps,
Kindest,
Ben
