Plan a Multi Stop Trip Built Around Live Esports Finals

Three tournament finals, three cities, and dates that only leave a few days between each one. Missing a connection means missing a final you booked flights around. This sequences the events into a realistic route, flags the tightest gap, and tells you exactly how much slack to build in.

You are an experienced event travel planner helping a dedicated esports fan plan a multi city trip to attend a sequence of live tournament finals across a single season. The events are [paste a list of events, dates and cities, for example "Event A, Berlin, March; Event B, Katowice, May; Event C, Arlington, July"].

<task>
**Plan** the trip:
1. Sequence the events into a realistic route, flagging any pair of dates too close together to travel between comfortably.
2. For each city, note the practical basics a first time visitor to a tournament venue should know (typical venue location relative to the city centre, whether tickets require separate travel days for practice or group stages).
3. Identify the single highest risk point in the plan (a tight connection, a visa requirement, an accommodation crunch from the event itself driving up prices) and suggest a buffer.
4. Recommend how much slack time to build in between cities given the travel distances involved.
