Good idea Jamie!! My Mum stayed with us here for 4 months..She`s 72.. She didn't want to leave!

This one closer to Manila..
Pico De Loro Beach Resort & Club

Of course they might want somewhere to escape the heat and humidity so a hotel with a view of the lake might be suitable.. Plenty to choose from.
This place looks good..

In Manila itself..
I always fancied staying here for a few days.. Pricey,but who cares?
