Most of the sleeping options here are in pensions and private rooms. These are usually rented out to vacationing families for weeks at a time, and they are unlikely to accept guests for 1 or 2 nights during the summer. Camping sites also line the beaches. During peak season, some of them resemble congested refugee camps. The official website of Hel (www.gohel.pl) has listings of rooms, chalets, and villas for rent. While Hel is fun for daytime window-shopping and eating out, rooms at the other resorts have better access to the beaches.
