Before weddings would almost always be done in Churches and then the reception would take place in either a hotel, a restaurant or at home. Nowadays, there are a lot more venues to choose from. Of course you can always opt for the conventional places (as mentioned here) but there are those who cannot be satisfied unless they're unique. There are those that get married underwater, while airborne, on moutaintops, etc. The more popular choice among Philippine brides of late are those in gardens or beaches. The beach thing is pretty understandable, afterall we live in a country surrounded by bodies of water. Even celebrities opt for this venue. And then there's the garden weddings, often held from late March to early June (mostly because these are the dry months) and then again in December. But of course hotels are still in season (and probably will never go out of season) because it is very practical to hold your reception in the same place where you prepped in as well, and maybe they'll throw in a complimentary overnight for the couple after the reception (depending on the package you chose and how good you haggle, hehehe) Here are a number of hotels and venues you can choose from:
but these examples are just the tip of the iceberg, there are a lot more you can choose from, just research it on the net or using an old-fashioned telephone directory and I'm sure before you know it, you're on your way to on-site visits and you're negotiating with the managers/owners of these establishments.
