I say pick the place you want to get married, regardless of anyone elses' opinions and then make it definite. Don't listen to what others say, it's YOUR wedding. If both of your sets of parents will be there, that is wonderful. Other than your parents, don't change your plans for people (and it sounds like your parents wouldn't ask you to change your plans). That being said, if you think you wouldn't regret it in the long run, I'd say elope if it makes you both happy!
