My follow up questions are as follows: does Crow, Erjohn and the other bus company that were mentioned travel via Coastal Highway/E. Aguinaldo Hwy to get to Tagaytay or do they take the South Luzon Expressway? From the information I read online, they recommend avoiding traveling via the Coastal Highway/E. Aguinaldo Hwy because of traffic congestion in the Bacoor, Dasmarinas, etc. (Cavite area?).
I guess my question would be: which air-conditioned bus lines travel the South Luzon Expressway (versus the Coastal Hwy/E. Aguinaldo Hwy)? Also does anyone know the approximate round-trip fare (Manila - Tagaytay - Manila)?
Thanks again for all your replies.
