To echo the Geek, you should elope but only if you are absolutely certain that your wife to be is fine with that. Weddings are part of a womans dream life from about the age of 3. Better to put up with whatever short term bullcrap a wedding throws at you than to shortchange your wife on something that may be very important to her. Plus its good practice for your new life of constantly putting up with short term bullcrap to accomodate your wifes wishes. Might as well start now. But whats the problem? You seem to have come up with a perfectly fine work around for your sisters religious needs. If she still wont go for it after going to the trouble of putting her up a mile from the wedding etc.. then Im going to side with Globe and say fuck her. Do what your future wife wants. Personally I would elope.
