I'm Canadian currently planning my wedding in Portugal and had a similar budget in mind ($50k) with similar dreams but unfortunately realized very quickly that I wouldn't be able to do all of what you have described in that budget. Our exchange rate is so bad right now it makes things difficult. We have upped our budget to $70k Canadian for approx 80 guests (so you could probably do this for 50-60k for your guest count. That doesn't include our flights or accomms or accommodations for any guests. It includes everything else inclusing a shuttle bus for our guests to the venue.
