It's probably the worst thing that tourists will encounter wrt Sunday's election.
After all the posts concerned about the election this weekend - "Is it safe?" (hello Singapore), it's time to remind tourists of what could most likely to ruin your holiday/vacation/stay ... the ban on alcohol sales everywhere from late afternoon Saturday through midnight Sunday/Monday. And yes, this means no drinks in hotel bars for around 30 hours.
So, if you're already there, go to the stores and stock up. If you're flying in on Saturday, consider duty free.
I landed in Bangkok last December on a Saturday evening, during a local/municipal election. Same rules applied, and the hotel made a killing on my minibar.
