Well
http://www.easyjet.com/en/book/regulations.html#delays reads:
16 Delays, cancellations and denied boarding [...] 2. If your flight is cancelled as a result of extraordinary circumstances [...] Where you choose to be re-routed at the earliest opportunity: 1. You will be provided with meals and refreshments in a reasonable relation to your waiting time; and 2. If an overnight stay is required because the reasonably expected time of departure is at least the day after the time of departure previously announced, easyJet shall offer you hotel accommodation and transport between the airport and the hotel free of charge.
So what do you think? Sounds all a bit vague to me. "easyJet shall offer you hotel accommodation" yes well... but am I supposed to book a four star hotel? I can't imagine they didn't come across that opportunity to exploit their terms
