Loch Lomond is situated near the west coast of Scotland and is an incredibly touristy area so the transport links are well established.
Driving
For those of you driving from the south of England, it's a long journey which will take you 6-8 hours depending on how many stops you make and your willingness to collect speeeding tickets. There are many service stations along the way, so organise your journey how you wish, however, I highly recommend the Gretna Green service station. Although it is fairly busy, it is on the Scottish border and has a lot of lovely walks in the area.
Flying
We recommend flying to Glasgow Airport, which takes less than 1 hour. You can fly out from Luton, Stansted, Heathrow, Gatwick, or London City. Here is a rough pricing guide for a return flight for the Friday - Sunday of the wedding. This pricing will change, of course but the cheapest to most expensive airports will remain the same(ish). It will save you 10-20% of the price by flying out on Thursday or back on Monday.
Stansted - Ryanair: From £72
Luton - EasyJet: From £107
Heathrow - British Airways: £124
Gatwick - EasyJet: £139
London City - British Airways: £154
Train
If you want to take the train, you can get a train from London to Glasgow in 4.5 - 6 hours via the Avanti West Coast operator (buy tickets from their website). It costs roughly £80-£100, but you'll probably save on the baggage fees if you are bringing a suitcase. All in all, it's a fairly similar price to a flight but a more scenic and comfortable journey. But also the flight times listed above are disgustingly early or late, whereas these train times are much more friendly. If you have a railcard, this price can get down to £55-£60, so it may be worth it if you're trying to save the pennies.
Once you are in Glasgow, you will want to get the ScotRail from Glasgow Queen Street to Balloch, which is a ~35-minute walk from Cameron House (or a 5-minute taxi). This will cost ~£8 each way (less with a railcard).
Helicopter
Haha...as if! No but Cameron House actually do have a helipad...(nuts)
