We got married in Nov and our AHR is in Feb. It is a full-on formal reception on a yacht, wedding attire being worn - especially THE DRESS!!, dances being done, cake being cut, photographer, DJ, candy buffet as the favors and after we make our grand entrance we will be showing the wedding video. I think its a great opportunity to celebrate with those not invited (co-workers) and those special people that couldn't make it to the wedding (close friends, family). Unless you have all your closest friends and family show up to your DW then a AHR is almost necessary. Most of those people want to share those special moments with you, congratulate you, see you in your dress, take pictures with you, etc. Make your AHR the way you and your FI/DH want it and just ENJOY!!!!
