Well google map isn't exactly accurate but is it safe to follow their instructions from thanon withhayu aka wireless road to the throne hall near to dusit zoo?

It says take bus 17x heading north then bus 72.

It is absolutely hopeless, I tried to find a bus number from Future Park Rangsit to Mochit, it just does not work. There is a bus stop at Future Park isn't there?

so should i look from the website?
