Welcome food

Hello all, we are having our ceremony at 12 midday. This is at a separate location to the reception, which is 13 miles away. I think by the time we've had some pictures, confetti throwing and guests have collected their cars, I would imagine it to be about 2 when we arrive at the reception venue (maybe 1.30 at a push). We will be having welcome drinks and have staff to set these up and serve if necessary. We are having food at 3pm. Do you think we need to offer snacks on arrival? The reception is on private land and we are having quite a relaxed, rustic, festival style to the day. I was wondering about something like popcorn, if needed. What do you think? Any ideas? Is anything needed? We're having fish and chips and Ice-cream for our wedding breakfast. There will also be a buffet and our cake at 8.30. Thanks.
