Great trip report Dave !
Reminds me a lot of my recent holiday there.
To answer your question about hotel rooms...yes, the price is for the room you'll be relieved to know, and 2 people sharing is fine.. Manila to Subic (Olongapo actually) is about 3 hours with a stop-off at the services for food and loos, but an interesting journey.
Congratulations on your engagement !
The province is totally different to Manila of course ( like comparing London to the Cotswolds etc), so well worth a stay there sometime.
