Hi Tashee. I did the surprise wedding and my sister did the small secluded island wedding in Fiji. Both were great and if you choose to get married my only advice is do what is right for you and DP and not for anyone else.
My need for plans is also extreme!! The plan rules supreme in our house. So by all means I say plan your compromise, bargain and arguments before the conversation starts with DP on the weekend.
I also agree one born every minute UK is much better than US. The US ladies all appear to always stay in bed. I can't imagine that I would like to birth like that. I hate staying still at any time, and imagine that I will be in the shower then on he fit ball then in bed then walking around!!
Good luck with your chat with DP on the weekend.
