Buffets are set to be "reduced to a minimum" while childcare could be organised by countries, TUI has warned.
As the popular holiday firm gears up to welcome travellers back to its hotels, it has issued a detailed 10-point plan outlining how it will operate.
For many set to travel abroad this summer, many of the attractions may no longer be available.
We take a look at TUI's new plans for holidays post-pandemic.
Entertainment
Only events, sports and entertainment involving small numbers of guests will be possible across its 400 hotels.
No night clubs will be open and an evening programme of events will take place in outdoor areas only.
Team sports will replaced by other activities such as golf and tennis, whilst football tournaments will be scrapped.
And they will have less participants but run more frequently.
Spas will also have to be adapted in line with health requirements, meaning less treatments on offer and no saunas.
More outdoor activities will be made available but with smaller groups.
And more private tours will also be on offer.
And Kids' Clubs "will be organised according to new standards in line with the requirements of the destinations and guests' countries of origin."
This could mean clubs could be limited by size or organised according to nationality.
Restaurants
In public areas such as restaurants, tables will be set 1.5 metres apart and will only be cleaned after guests have left them.
They will have limited capacity to ensure social distancing rules are followed, but the opening hours will be extended.
And the hugely popular buffets will have to be served to you by a member of staff with no self-service option.
Staff will have to wear masks when serving food and drinks to guests.
Hotel organisation
Holidaymakers will be encouraged to check-in online via the hotel's website or their smartphone.
More digital services to reduce unnecessary touchpoints.
More private transfers will be offered and vehicles will be cleaned for every journey.
In public areas such as in the restaurants, corridors or gyms, all staff members will be required to keep a distance of 1.5 to two metres between them and the guests.
The number of disinfectant dispensers will be significantly increased.
All rooms will be thoroughly deep cleaned before the arrival of guests.
The most frequently used areas, such as bathrooms, and most used devices and appliances like TV remote controls "will receive particular attention".
And staff will "work together in fixed teams to reconstruct possible infection chains."
The holiday chain says it will train all employees in its own hotels.

The travel operator has said the plan will be introduced across TUI Blue, Robinson and TUI Magic Life and its hotel partners.
In a statement on its website, the UK firm said: "It is part of a more comprehensive package of measures that covers all of the tour operator's service components, from retail , flights and transfers to hotel stays, local excursions and cruises."
Sebastian Ebel, the member of Tui's group executive board responsible for holiday experiences, said: “Customer surveys clearly indicate that safety and hygiene will be of paramount importance for holidaymakers after the lockdown”,
"With our group-wide, integrated health and safety management system, we can ensure that our hotels meet guests’ high expectations and offer the best possible protection against infections during these unusual times.
