Hi! We're using china and glassware for our sit down dinner. The caterer suggested hard plastic cups for the bar, but I'd rather use glassware. The issue is that we'd either need a lot of glasses (full bar including bubbly and 100 guests for 8 hours) or wash them. There's no water in the reception area, so the only solution I found is a portable dishwasher with a water tank. Then someone would have to wash dishes all night (we'd hire someone for that). Any better ideas/solutions? Beer will be served in bottles, so I'm thinking we just need lowball or rocks glasses and stemless wine glasses if we rent. Would we need champagne flutes for the bar?
