Good rates have been obtained with two hotels in Puerto de la Cruz, very close to the conference venue.
All prices are per person, per night in a double room.
Supplements for single rooms are also specified. The cost is 1075 pesetas. If the times are not right for you, you can catch bus 341 to the main bus terminal in Santa Cruz, and then change over to bus 102 which will take you straight into Puerto de la Cruz. The price is 470 pesetas. There is an uphill stretch from the bus terminal in Puerto de la Cruz to the hotels, and for this we recommend a taxi.
