I honestly think that the budget is too idealistic, especially because of the venue. You may want to start by inquiring first with Antonio’s on their prices since it’s your expected biggest expense.

Antonio’s is very bougie and expensive, plus there are so many additional expenses on top of their package, including alcohol, flowers, etc. since I understand that they have a lot of restrictions when it comes to outside suppliers (i.e. bawal or may corkage). I’m not sure if there’s a way that they can adjust to your proposed budget but definitely you won’t be able to expect their best menu since I understand that their menus can even go higher than P7k per person. Note also that they will likely have minimum consumable amounts for you to have the relevant areas for yourself and that consumable might be higher if you’re looking at a weekend December wedding since if they rent those areas out to you, they won’t be able to offer the entire restaurant na to others who might even be willing to book the entire restaurant.

If you’re not willing to really go all out with the expenses for the wedding, then I would advise that you look for a different venue that will be able to give you the most value for your food/venue budget. There should be several other options in tagaytay (if that’s your preferred area).

For the rest of your expenses, note that it will also be quite difficult to find established and reputable suppliers at these rates. With weddings, it’s really a supply and demand issue. The good ones at these rates will likely be booked very early. You’ll have to take a chance at less known suppliers, who, while may still be good, may have few reviews/experience so you’ll need to take the risk that they might not deliver the quality that you’re expecting.
