Hi, jackycrazy.
I'm currently a student at Monash (in my 4th year now), and this is what I can tell you.
The eastern parking (the free one) is good in the sense that it's free, however the conditions of the roads in that parking is not in top condition. The western parking (RM2 parking) will cost you money, but it may be worth paying the RM2, as the security there looks to be slightly better than the one at eastern parking, plus the road condition is much better, so no need to worry about your car tyre puncturing or whatnot.
I never tried the new sunway carpark, but yes, you'll be able to take the canopy walk to Monash. However, you'll have to walk much more than compared to the western and eastern parking. For 8am classes, this obviously isn't the best choice.
Of course, the eastern parking will be the most crowded, as it's free. For me, during the semester, I use both. If I have an 8am class, I'll be able to park at the eastern parking. However, if my class starts a bit later (eg. 9 or 10am), then I have no choice but to use the western parking.

For tomorrow, if you come at 9.30am, I would guess that the free parking would be full already, as the number of new students and parents would easily fill the free parking. So probably you'll have to pay RM2.

I'll be at the orientation tomorrow helping out, as one of the members of the student council. Hope you have fun this week in orientation!

Science!

BSc, doing a double degree. Biotech and biomed. That's why 4th year is possible.

yup, Msian campus. Thanks!

Yup, classes start on Wednesday. Both today and tomorrow is public holiday, so no classes.
