Tui and sister brand First Choice are offering discounts of up to £200 as part of a post-Christmas bookings push.
A zero deposit offer also applies to Tui summer 2020 deals issued today (Boxing Day).
Marella Cruises is also luring potential customers with £200 off summer and winter sailings between May 2020 and April 2021.
A similar level of discount applies to new Tui river cruises on March to October 2020 departures.
First Choice claims to have “thousands” of holidays available for less than £299 per person valid on bookings made by January 2.
The First Choice deals come as the operator switches from being all-inclusive only to providing mainstream package holidays wth board bases for different budgets.
