"You are likely to need to self-isolate wherever you become a close contact or test positive, so there may be extra costs involved in paying for additional accommodation and changing your travel plans."

Yesterday was a record day for booster shots across New Zealand, with 66,864 doses administered, taking the total so far to more than 1.5 million.
It comes as 1 million Kiwis yesterday became eligible for their booster after the interval was reduced from four to three months.
The MoH has urged: "If you're over 18 and your booster is due, please get it now."
As of today, more than 90 per cent of Hawke's Bay's Māori population have received their first dose of the Covid-19 vaccine. Twelve DHB regions now have more than 90 per cent of Māori partially vaccinated.
The number of vaccines administered to date across the percentage of eligible New Zealanders is: 4,046,832 first doses (96 per cent); 3,971,743 second doses (94 per cent); 1,511,766 booster doses (49 per cent).
There have been 192,661 first doses of paediatric vaccines administered to date. This represents 40 per cent of 5 to 11-year-olds in New Zealand.
Covid-19 modeller professor Michael Plank yesterday said although Omicron infections had so far risen slightly slower than in many other countries, case numbers were still doubling roughly every four days.
"It is likely we'll see record cases numbers very soon, if not [today] then I think it will be within the next few days."
Plank said it was too early to predict how New Zealand's Omicron outbreak would pan out.
So far the average daily case numbers had doubled about every four to five days, whereas they had doubled every two to three days in some countries.
If New Zealand can keep the doubling of infections to the lower end of that scale, it will be quite good by comparison, he said.
"We'll also find that our red traffic light system and the measures people are taking are doing their job, which is to slow things down and spread out the load on our health systems," he said.
Daily numbers were still far below earlier modelling tipping as many as 50,000 new cases could be emerging by Waitangi Day.
However, as pandemic-weary Kiwis seek a more normal life involving unimpeded overseas travel and no lockdowns, Prime Minister Jacinda Ardern yesterday urged against complacency.
The threat of infection spread has triggered a warning to holidaymakers in a week which has seen Auckland once more become the nation's Covid hotspot.
Officials warned this week that travel contributed to the spread of the infection and said it was important people going away took measures to reduce the risk of both catching and spreading the virus.
