We are a group of 11 pax. My wife & i are the lead for this trip & our parent, uncle & aunties are in their late 60s to early 70s. For safety reason we had decided not to use Grab as our mode of transport because we do not want to separate anyone from the group. We had planned to book our day trips online but some of their trips can only accommodate maximum of 8 pax. Does anyone have contact for reliable private driver or tour company that provide vehicle or day trips for 11 pax or more.
