As an introduction to Iceland, the first thing you have to know is that the prices are quite high and the demand outweighs the supply, so it is very important to book accommodation, the travel package or the motorhomes well in advance. In some places on the island, such as the south and southeast of Iceland, all options are sold out several months in advance. As for the prices, some accommodations consider the middle season the months of May and September, while for others it is already high season, so the prices are more expensive. The low season takes place during the winter, between the months of October and April, although it is also the most popular time to see Northern Lights. During these months some hotels around the island remain closed, as well as campsites, so it is not easy to find accommodation and you can not leave it till the last minute. Moreover, hotels in Reykjavík are usually filled even more. For example, if you want to travel to Iceland on New Year's Eve, you have to book your accommodation in the capital several months in advance.
