Withdrawal by consumer pursuant to regulation 12 and cancellation by organiser
13.-(1) The terms set out in paragraphs (2) and (3) below are implied in every contract and apply where the consumer withdraws from the contract pursuant to the term in it implied by virtue of regulation 12(a), or where the organiser, for any reason other than the fault of the consumer, cancels the package before the agreed date of departure.

(2) The consumer is entitled-

(a) to take a substitute package of equivalent or superior quality if the other party to the contract is able to offer him such a substitute; or
(b) to take a substitute package of lower quality if the other party to the contract is able to offer him one and to recover from the organiser the difference in price between the price of the package purchased and that of the substitute package; or
(c) to have repaid to him as soon as possible all the monies paid by him under the contract.
(3) The consumer is entitled, if appropriate, to be compensated by the organiser for non-performance of the contract except where-

(a) the package is cancelled because the number of persons who agree to take it is less than the minimum number required and the consumer is informed of the cancellation, in writing, within the period indicated in the description of the package; or
(b) the package is cancelled by reason of unusual and unforeseeable circumstances beyond the control of the party by whom this exception is pleaded, the consequences of which could not have been avoided even if all due care had been exercised.
(4) Overbooking shall not be regarded as a circumstance falling within the provisions of sub-paragraph (b) of paragraph (3) above.

Significant proportion of services not provided
14.-(1) The terms set out in paragraphs (2) and (3) below are implied in every contract and apply where, after departure, a significant proportion of the services contracted for is not provided or the organiser becomes aware that he will be unable to procure a significant proportion of the services to be provided.

(2) The organiser will make suitable alternative arrangements, at no extra cost to the consumer, for the continuation of the package and will, where appropriate, compensate the consumer for the difference between the services to be supplied under the contract and those supplied.

(3) If it is impossible to make arrangements as described in paragraph (2), or these are not accepted by the consumer for good reasons, the organiser will, where appropriate, provide the consumer with equivalent transport back to the place of departure or to another place to which the consumer has agreed and will, where appropriate, compensate the consumer.
