A man quarantined in hotel in Tenerife has said none of the Brits staying there "feel safe".
The Derbyshire man had travelled to the H10 Hotel for four nights with his partner when news of an coronavirus outbreak began to spread.
They were due to fly back on Tuesday but are now being held in quarantine.
The guests, including 160 Brits, will remain under lockdown at the four-star H10 Costa Adeje Palace in the south west of the Spanish island until March 10.
The 60-year-old said: "We have been told to stay in our rooms but the hotel has no way of enforcing it.
"We have a WhatsApp group for all of the Brits and we don't feel safe. We think this is going to end up worse than that ship (the Diamond Princess).
"I don't think confusion would be the right word to describe it - they are just not able to enforce quarantine conditions.
"People are able to walk around the buildings and some are even going in the pool."
The Brit said that people were interacting with each other while not wearing masks.
"They served a buffet-style dinner last night, and people were milling about without masks, touching utensils - the virus is bound to spread," he continued.
"It's totally crazy. We feel we are just being quarantined until we eventually get it [Covid-19].
"No one seems to be helping, and the consulate aren't helping us - why can't they bring us home?
"We are in a quarantine that is not being followed and it is not safe."
His fears for his health have been intensified since staff on the front desk were unable to get him a resupply of medication he needs
The El Pais newspaper said 800 guests from 25 countries are in the hotel, along with around 200 workers.
Two security perimeters remain in place, while a "field hospital" has been set up to treat anybody with coronavirus symptoms.
Other guests, including Hannah Green from Hertforshire, said that nobody had come to take their temperature.
The 27-year-old said: "Everyone got tested yesterday - last night. They had their temperatures taken, except us and another couple so far that we know of.
"If we go out on to the balcony, the couple that we can see on our right hand side, they haven't (been checked) either, so it's our two rooms together.
"I was really upset this morning that the doctors hadn't been to see us. I feel like our son should be a priority because he's a baby."
Nigel Scotland reiterated concerns about guests ignoring advice to stay in their rooms.
"I counted 268 people on sunbeds," he told BBC Radio 4's World at One.
Mr Scotland said there was a lack of communication from UK officials about what happens next.
He said: "We haven't heard anything. Our great hope would be to be flown home quickly, because we probably have to do another 14 days of self-isolation when we get back."
Alex Jones, from Stafford, is at the hotel with his wife Jodie, 38, their eight-month-old daughter Lilly, five-year-old son Oliver, and his wife’s parents and sister.
Mr Jones, a gym manager and photographer, said a small number of guests aren’t bothering to wear masks outside of their rooms.
He said: “99 per cent are wearing masks. There are some people who feel they don’t need to wear a mask.
“The staff don’t have the remit to enforce it [the advice] on a thousand people."
Mr Jones, 40, said his family has decided to err on the side of caution and spend most of their time confined to their room.
When they do venture out to go for a walk or get food, they wear protective gloves and masks, and wash their hands when they return.
They are staying out of the swimming pool and they are avoiding close contact with others.
He told Mirror Online that they are concerned that guests could be carrying the virus, but added: “Unfortunately, it’s one of those things where it’s invisible."
Mr Jones said the British guests don’t know yet if they will be forced to spend another 14 days in quarantine when they return to the UK.
It “would be good” if the UK sent a plane to rescue the Britons at some point, he said.
He added: “They’re in a bit of a catch-22 situation, it’s a bit of a no-win.”
The family arrived ten days ago and were due to fly home on Tuesday this week.
Mr Jones and his wife have been keeping their children occupied by playing games, drawing and colouring, and watching films.
“The main thing is making sure everybody is safe,” he said.
He hailed the hotel and local officials for the way they have handled the situation.
Hotel staff have been paying special attention to the Joneses because they have young children, taking the time to source baby food for Lilly.
He added: “The hotel and the authorities should be commended for what they are doing. It’s not an ideal situation.”
