I always re-activate my account at http://www.asianescapades.com/ prior to a trip, filled with reviews, current goings-on as well as current pics, you do have to pay though.
If you don't use a Hotel to pick you up in Manila I'd suggest these guys: http://www.margarita....com/update.php pretty reliable and have a good rep, used them on my last trip.
Beisdes Orchard Inn noted by Coss there's also http://www.wildorchidresort.com/ - great location with two pools, Stayed there last spring. Walked up to Kokomos for most of my meals, great place for people watching.
Have some Pattaya Expat friends living in Pattaya, AC is where they go for vacation :-) Many say you get WAY better GFE in AC and LT's the rule there (vice ST). Hopefully they'll be a "Pool Party" going on somewhere during your visit, should bring a waterproof camera if you go :-)
