As you know mate, exactly what i did. Got married in Mexico, with only my son, mom & dad, Sister & her boyfriend and Mrs. Wig's mom & dad and obviously the missus. Then had a 'do' when we got back with 100 or so people there.
So glad we did it this way, saved a fucktonne of money and felt more intimate than a full blown wedding over here.
Each to there own, but it felt more special doing it that way.
This is pretty much my thinking too.
I'm loathe to spend £10k - £20k on a single day when there's a whole world out there that could be explored for similar money.
I really do like to idea of having a small, intimate wedding and then throwing a really good reception at a later date.
I'm not really one for tradition anyway, and neither is my other half, so it definitely sounds like the way forward.
I will say mate, even doing it this way, you still dont get much (if any) change out of £10k. Depending on where you go & for how long obviously.
Still cheeper than the traditional way of doing things.
