Your sister will be still here right? Also, on the weekend, I
will be quite happy to take you around.
Last year when my friend came to visit me from Brunei, I asked him
to catch the airport bus to the city to meet me. There were 2
reasons to that.... one he arrived in the afternoon and I was still
working. Two, it was cheaper for him to catch the airport bus from
the airport and since he didn't have much to carry with him.
The airport bus only costs about $15- $20 each way. If I were to
pick him up from the airport (assuming driving from city only) it
would cost me at least $10 to go through the tunnel, $10 for the
petrol and at least $20-$30 for the carpark at the airport.
Anyway, I did take him to the airport when he left since he got
tonnes of things to bring back. Also, since I am not going to see
him for a while, it's good to be able to see him off.
