Keep your self organized.  Record all payments you have made and all upcoming payments due, keep all signed contracts and update your vendors as soon as a change is necessary.  Get all changes in written form and keep everything in one location.

Once you have worked out your budget, stick with it.  Keep track of the finances as you go, so you won’t be over budget later, when it may be too late.

Shop around for your vendors.  Find the companies that will work best with your ideas, budget, guest count and tastes.

Keep your guests in mind when selecting your vendors.  Are there any mobility issues, adequate restroom facilities, any dietary restrictions, will the children be entertained, is there enough for everyone to be comfortable, can they accommodate your guest count?

If your event is in an unfamiliar location, or you have a lot of out of town guests, make sure everyone (guests and vendors) have a detailed map and an estimated travel time to the event.  You might want to consider valet parking or bus rental to make it easier.

Make sure your rental reservations include a few extras.  You may have a few unexpected guests or breakage.

The weather in Montana always keeps us guessing.  Do you have an inclement weather plan?  Ask your venue, caterer and rental company for their suggestions- they will know how to handle it best.  Not to mention you will get some good stories too.

Ask for help and advice whenever you need it.  It is what your vendors do.

And finally, the most important tip- relax, have a great time, dance to the music you selected, enjoy the menu that was prepared for you, and spend time with the people who are there to see you.
