Porterage service is not common at the Camino. Some hotels in the bigger cities might offer it for an extra fee. But in the small villages along the Camino this service will not be available.
Please note that the hotels are not committed to bring your luggage to your room so it will be up to you to carry it to your bedroom. In some cases, accommodation may not have a lift and you may have to carry the luggage up the stairs so we recommend you pack light.
