First off- my wedding is an outdoor very green/tropical style venue- all outdoor with palm trees banana leaf trees but also has a fire pit and some casual accents. I found these pretty stemless glasses online at the dollar tree and ordered about 50 so far.
We want to have the following drink options:
1. White and red wine
2. Keg of beer
3. Keg of cider (brides favorite)
Our wedding overall is going to be on the nicer side in terms of decor, long dresses, linen table cloths etc so I think that the classy move would be to get the nicer clear glasses. BUT we are also fun people and I love a good Solo cup so I think we should get silver solo cups like these:

Annnnd these are the wine glasses if you chose wine:

Is that an awkward combo? The decor is mostly blue tones and boho with some silver accents.
My FW also thinks that the glass will be problematic cause they will get left everywhere and we will have to figure out what to do with them after the wedding. Any insight from people who purchased glasses would be helpful.
THANKS!
