Where should you travel in Sri Lanka in September — south coast (Unawatuna) or east coast (Trincomalee)?

One traveler mentioned that during a local holiday the main street in Unawatuna got so crowded that they had to walk back to their guesthouse via a jungle path instead — tiring, but it let them avoid the festival crowds.

In late July travelers debated whether to spend a whole month of August in Trincomalee or stay in Unawatuna — experienced travelers leaned toward staying on the south coast (Unawatuna) for a longer trip during that period.

By September there's no point heading to Passikudah or Trincomalee — all the tourist action and nightlife will be concentrated on the south coast: Unawatuna, Weligama, Madiha and Hikkaduwa.
