Well I hope I'll get called the day before but not betting on it!
Reason we wanted to travel together is all of us have never been to some of the places and last thing we want is to be separated because the driver may not know where the place is, which I may just be over thinking!
I have heard mixed information about what is big car is available at Dubai, on Emirates website it says they have Viano, some other people said they have been on a cadilac, the call centre told me no big cars in Dubai but when I called again someone else said they have station wagons but leave the decision to me as whether it will fit all of our bags. I thought if we end up getting cramped into one car in 40 degrees heat, might as well have more breathing space in 2 cars
Hopefully it will all work out!
