Elope, then have a party and get there first to welcome everyone.
With the best will in the world, if you don't like being the centre of attention, being a bride in a traditional wedding, even with a fairly modest number of guests is probably not for you. You will be the centre of attention all day, peaking at the entrance, the exit, the entrance to the venue, any posed shots with family, the speeches, the cake, the first dance. If you're going to be dreading all these things, don't do it to yourself.
People with the best intentions, will be trying to grab you and kiss you, and ask you about shoes, dress, tell you your hair looks amazing, it's like being a minor celebrity. I'm not a fan of attention either and I will not lie, I couldn't wait for the day to be over and get out of there away from everyone if I'm totally honest.
Unless it appeals, it's a hell of a lot of money to spend on a 12 hour ordeal, and it's really not compulsory. At the least, keep your numbers to a bare minimum and ask for no phones, get one friend you trust to snap some and set up a website where they'll be shared after the event.
