I'm getting married in a few weeks at MDC... I'm so excited and I'm just working on making sure everything is done and ready. I've been in the planning process for a year so I can't wait to see how it all comes together. I'm happy to report back after the wedding to let everyone know how it went and provide any tips for future MDC brides. Regarding your questions....
1. We are packing suitcases with all of our welcome bags and goodies, favors, etc. We booked all of the rooms at MDC so we have a lot to pack. It looks like we'll have at least 3-4 large suitcases full of wedding stuff and our clothes, etc. Several friends and family have offered to take a suitcase for us so once we are all packed we'll see if we can manage to take it all ourselves and if not we'll have a friend or two take a suitcase for us.
2. We were thinking of doing a group excursion but I think we are just going to do an informal trip to Ricks for those that want to go but I know Kerry is happy to arrange any type of excursion you want to do.
3. We are doing a welcome dinner on Friday night (we get married on Saturday). We aren't planning anything fancy for Friday and we are just having guests order off of the menu at Annies for the dinner meal. We are getting a steel drum band for an hour on Friday night to play at the welcome dinner. I'll let you know how they are (Kerry is arranging it, I'm sure they'll be great). We are using a DJ for the ceremony music and then we having PACE band for three hours during the wedding reception.
I'm not sure if that helps but good luck planning and I'm happy to answer any questions that may be helpful to you.
