We have a dd aged 3 and want to get married this spring. We don't want the expense of a large wedding (big family) and have decided to just invite our parents and our dd. The rest of the family would want to come if they knew so we have decided to do this:
The secret bit of the plan
Ask each set of parents (unbeknown to the other set of parents) if they can come over to our house to babysit dd for a few days while we have a mini break (this has been offered to us before- am not just taking the piss 
). Once they have confirmed they can do the dates we are going to ring them a couple of days before to ask that they bring something nice to wear as we are taking them out for a meal just before we go away to say thank-you. This will obviously be their wedding outfit, and the going away will be our honeymoon/mini break.
Now, our plans start to fall down a bit...
Both sets of parents will turn up, lets say day before wedding (I'm worried if we leave it until the day Fil may suddenly go into work, day before at least gives us some leeway) . They will see other set of parents and wonder why they have also been asked to babysit. The house is too small for both sets to stay over. So, at this point, we'd probably have to say "we've booked you in at the local guest house, we getting married tomorrow". And then they'll no doubt be wanting to call our siblings etc. DM and MiL will probably want to head straight to the shops to choose a different outfit . I worry they'll all be flustered by it and we'll spend our wedding day trying to calm other peoples nerves!
the day itself
Get a taxi to very nice licensed wedding venue/hotel. Take vows in a room that is too large for the number of guests (can you tell that his is worrying me, billy no mates etc etc) have vair nice meal, champers, leave dd with whichever parents want to complete the babysitting arrangement for next couple of days, get taxi to train station, train to London (2 hours) hotel in London for night, Eurostar to paris for short break
my worries
The 'secret' element. Parents might not pack a nice outfit (doesnt bother me, but would bother them). They might arrive as just one half of the couple e.g. Dad of FiL might not turn up. Siblings might be a bit peeved.
The actual ceremony. How to get it to feel intimate and special rather than just a few people in a large room mostly tending to or distracted by our 3 year old.
The meal. Want it to feel like a wedding meal rather than just a pub lunch. For instance would be gutted in FiL moaned about the food (likely).
So. What do you think? Are we mad? Does this sound like a workable plan? Got any ideas to make the day feel more special?
PS -wish me congratulations, you're the first to know!
