Do you think this is too cheap or should I change it?

I am having a simple beach wedding. My budget is tight so we have been trying to spend very little and still make it nice. We are having our reception at Coca Beach country Club. It's a nice place but not a big fancy ritzy country club. I am definitely getting cloth linens because I think it would be tacky to use paper or plastic at a nice place. We are doing a buffet style dinner. With meat , smokies, wings, shrimp, cuban sandwiches and club sandwiches, pasta salad and some other things. We went and found out how much it was to rent the plates and it is way out of our budget right now. We got these nice clear plastic banquet plates with matching cake plates, clear plastic silverware and nice white dinner napkins. Now this is a laid back simple beach wedding. Is it going to be OK to use plastic? I got the better quality so it looks nicer. what is your opinion considering the cirstances and that it is a simple beach wedding?
