I did it in less than 3 weeks, as I was prepared.
The only thing that we had to wait for, was the marriage licence, 10 days.
Everything else had been organized by me online, and by my wife doing the legwork with "small" details, like wedding dress, Barongs, Maids dresses, and paying the deposit at the hotel.
Arrived sunday 4th feb, applied for licence on monday the 5th, married on monday 19th, left on the 23d.
Easy.....
You have lots of time to plan ahead, only forget Xmas time.... Try to go in January
