Ummm, my apologies for this. I've been getting sidetracked, and I let myself forget how we wanted to set this up. Now, hopefully, I'm back on track.
Wedding and feast: For both the wedding and the feast, we'll invite Sir Rodric and Lady Habren, as well as Merlin - as originally planned.
Wedding: I would like to send an invitation to Sir Cedwyn and Lady Ysbail as well - just in case there's the possibility of them feeling slighted by not inviting them - but as I mentioned before, the invitation would come with a separate letter to inform them of the pagan rites surrounding the wedding, and a reassurance that we would not be offended if they chose to decline.
Feast: Invitations to Sir Cedwyn and Lady Ysbail, as well as Earl Roderick.
Timing of marriage and feast: As Holmg?r?r suggested, we should have the marriage and rites separate from the actual feast. We can have the feast a day or two after the marriage and rites.
Expenses: Beyond the food and drink, what else should be be looking at? Singers? Jongleurs? Lutists? What about places to stay for the non-Nord guests that we invite? I was thinking that one of the two lodges could be spruced up some more . . .
