Batangas, Philipines

Hi,

We are going to the Philipines the week before christmas, and originally we
had planned to spend this week on Boracay. Yesterday we recieved an offer
from a friend's friend, where we could stay for free in her summer house in
Batangas.

So my question is, how is Batangas for a 30-ish couple without any prior
experience traveling in the Philipines? We originally opted for Boracay
after seeing a Lonely Planet Pilot Guide on the Travel channel, but one week
of free accomodation is very tempting...
Should we spend lots of money staying in (and flying to) Boracay, or should
we go to Batangas?

This is supposed to be the "beach week" of our month in SoutEast Asia...

Sincerely,
HH
