Cocktail Hour

My fiance and I are getting married on a large farm. The ceremony will be held in an apple orchard and the reception is in a barn on the property. For the cocktail hour we wanted to have it under this pavilion in a garden on the property. The farm is so large and we want to try to take advantage of all the beautiful space. Because these spaces are a little further apart I think it would be difficult for our bartenders to drag everything needed for drinks during cocktail hour to the pavilion and then back to the barn for the reception (it's an old barn and we need everything, including coolers filled with ice). We plan to have a few types of beer and some mixed drinks for the reception. So I was wondering if it would be a good idea for the cocktail hour to do maybe a special drink for the cocktail hour like an apple sangria since we are getting married in the apple orchard. And just have light snacks of cheese, meat and cracker trays. Our cocktail hour isn't long and dinner will be served right after at the start of the reception after introductions, so we didn't want anything too heavy. Would this be a good or bad idea?
