My mom and did a lot of things ourselves. We made buckets of flowers for hanging on shepherds, the centerpieces, programs, tags for the favor, ring bearer pillow. We had a great time but...
Ryan's (husband) family is from out of state and we wanted a BBQ for the rehearsal dinner. We had it catered at a park. BIG MISTAKE!!!! My mom and her friends ended up doing all of the work. Ryan's dad paid for it but my advice is this--just go to a restaurant then you don't have to worry about setting up/cleaning up etc. Granted if your MIL is around town and has done a rehearsal dinner before it would probably be ok. Also Husbands fam i s from South Africa so they have no idea what should be done for rehearsal dinner.
We decorated the vineyard ourselves with the help of maids and mom's friends--it looked good and did not take too long.
TENTS-My coordinator had some 10X10 pop up tents that she rented to us for about $40 for 3 tents. The vineyard also had one which the DJ was going to be under. Well on June 12th there was a severe thunderstorm and all the white tents except one was destroyed in the storm. The only one that made it did so b/c my dad went out there to hold it down! I have a great dad! So I would say go ahead and pony up the $300-400 to a rental company. If the tent gets destroyed it is on them not your parents to replace.
I feel like maybe my mom didn't have as much fun b/c she had to help clean up afterwards.
So if you have the money maybe getting married at one of the expensive places where they do everything is better. My mom and I did have quite a bit of fun getting ready for the wedding but it was a lot of work.
