Small Limoncello Wedding Favors: wwyd?

I have started making limoncello for my wedding favors and I am second guessing myself. I originally bought 72 small (2 oz) bottles to fill with my homemade limoncello. We have 100 guests and I envisioned most would take one per couple, two for people who are really interested.

Now the bottles are looking small and I'm waffling on how to move forward. I am torn between the following options:

1. Leaving as is because nobody wants two little bottles of limoncello anyway, and likely the second will just be thrown away.

2. Getting more bottles, making more limoncello and offering one bottle of limoncello per person so that it looks better.

3. Getting more bottles and filling then with chocolate covered espresso beans, enough so that everyone can have something if they don't like limoncello.

I feel like all these decisions seem important right now and then I'll just be left with a ton of filled little bottles that nobody wants 🤦🏻.

What would you do??
