For me this is also influenced by the amount of time I can get off work. Having booked a 3 week trip to Philippines already, I would have to wait until next year to get enough time to get married in Philippines without rushing around organising and then flying back the day after.
A fiancee Visa for us will work better, giving us more time in the Uk to get everything sorted without panic. We can then fly to Philippines next year and have plenty of time for a blessing ceremony and celebration in a more relaxed fashion.
