It depends on which bridal shop you sign up with. As per my knowledge, local bridal shop with overseas package they will get a few couples together and take together. So for this kind normally this price will not be much diff as what your partner see.
If you sign up with overseas bridal shop then will depends what kind of package you take from them. normally the additional cost will be the transport and bringing out the make up artist with you. but one thing is if I am not wrong will be on one to one instead.
some even have overseas branch but not sure if its going to be one to one (means one couple to one photographer). If this is a concern to you both then this should be one of the questions you should ask before signing up with them.
the other thing is some of overseas studio package will not be able to include your AD photographer and make up artist which nomally local studio will provide. oh also the car deco and hand flowers. lots of small things into consideration and most of all on your budget too.
Good luck
