How many codes do you need for sun holidays?

Excuse me, could you please clarify what you mean by "codes" for sun holidays? Are you referring to some kind of promotional code, a voucher, or perhaps a specific type of code required to book a holiday in a sunny destination? If so, the number of codes needed would depend on the specific offer or promotion being advertised, as well as the number of people in your travel group. Could you provide a bit more context or detail about what you're asking?
