Honestly I think it just depends what is important to you, and what you want out of your wedding day.
Me and 3 of my friends were all wedding planning last year and all had/are having very different weddings!
For DH & I the most important thing for us was having our family & friends there to celebrate with us. Sadly both of our grandparents are unable to fly for health reasons so that pretty much ruled that out straight away! We had a UK wedding and absolutely loved it, we picked somewhere local so it was no hassle for any of our guests and we had a venue that was ours for the whole day, ceremony, 3 course meal etc, I’d describe our wedding as probably very “traditional” and we absolutely loved it!
In contrast, one of the others also had a UK wedding but to keep costs down had a twilight ceremony and that meant instead of there being a 3 course meal, they just put a buffet on later on and that was lovely and worked perfect! It was an amazing wedding for a fraction of the price of ours so I would definitely consider that!
With abroad weddings you really need to think about what you want it to look like and what is reasonable. For example one of our friends getting married in Cyprus has been very strict about no guests, they just want it to be them and their parents, then having a function room evening do back at home. The whole thing including the holiday has cost them less than £3000- which is literally cheaper than our venue alone!
However our other friends who are having their wedding in Greece wanted an abroad wedding but also wanted/expected friends and family to attend. They did give notice so tried to argue that people had time to save to pay for it but the reality is that everybody has their own things going on, people are saving for houses, for their own weddings, for babies, even just saving for holidays somewhere they choose to go. So I think if you choose an abroad wedding you have to do that on the assumption & acceptance that it may just end up being you, your partner and a couple of witnesses. If you’re happy with that then go for it!
I think the best thing to do is sit down properly with your partner (once he actually pulls his finger out and puts a ring on your finger!) and discuss what you actually want your wedding day to look like/be like, is the destination more important than who ends up being there for example? Are you bothered about it being a whole day event or would an evening/twilight package do? Once you have agreed on the basics then you can look at your options :)
