The Wedding Channel even offers a service on their Web site that makes hotel arrangements for out-of-town guests and guarantees them the lowest price.

After the hotel has been booked, car-pooling would be the next best option for saving money.

If the wedding is too far away to drive, then use an online tool like Expedia.com or Orbitz.com to find cheap airfares. Using a wedding excursion as your vacation will also help your savings account in the long run.

"It's becoming more common for weddings to be out-of-town. Couples want that memorable wedding day at a memorable place, unfortunately it can make it hard on the guests," Crouse explained. "So, intelligent budgeting can help a guest. It's not improper to use the time as a vacation. In fact, I see guests doing it all the time."

Lastly, clothes can be an expensive part of a wedding. Some couples have strict attire policies, while others do not. Obviously, one of the best ways to budget multiple wedding invitations is by purchasing one spectacular outfit and wearing it to all the weddings.

"The only time one outfit can become a problem is when the other guests at the wedding are the same people at all the weddings you need to attend. No one wants to wear the same dress or suit to four different weddings when everyone there saw you wear it to the last three," Crouse added. "That's when thrift shopping comes in handy."

A thrift shop, according to the Wedding Channel's Web site, is just a shop that sells used goods (especially clothes) at a low price. Every town or city has at least one up-scale thrift shop, where amazing clothes can be found at a decent price.

"Be wary about the clothes you're buying, though. You want to look nice, so only skimp until it's noticeable. The best way to make money go a long way with clothes is by accessorizing," Crouse said. "Sometimes jewelry, shoes or a belt can make a dress look completely different and new."

So, now that you have opened all your invitations, there are just a few things to remember when budgeting for the stressful wedding season: stick to the registry and shop early, turn a wedding into your vacation and thrift shop 'till you drop or make one outfit go a long way. With all of the resources and tips available to wedding guests, it's easy to save money and spare the piggy bank when entering the wedding season.

"Weddings should be an enjoyable thing to remember," Crouse said. "So, just try to have fun, budget wisely and make the best of the situation."
