What changes if you change an input
- Month: the same trip in May is estimated at 3,300 GBP and in December at 3,800 GBP, all other inputs held.
- Travellers: rooms are counted at two people per room, so 2 travellers is priced as one room. No child age or child discount is modelled.
- Trip length: 12 days includes 11 nights of accommodation. Changing the duration changes lodging and other on-the-ground spending; the modelled return airfare stays fixed when the other inputs are unchanged.
- Travel style: this page prices the Mid-range style; a cheaper or richer style moves lodging, food and activities together.
