Hi,
I suggest to undertand well what the interviewer is expecting from you. Some of them they just see it as a little game and would be happy to see you making up some numbers on the supply side. For example, you know there must be more than 100 hotels in London. Is it reasonable to assume there might be 1000? Once you get that number, you can assume an average maximum capacity and get a quick answer.
If you have to offer a more developed answer, try to be creative and create bottlenecks. For example, in the case of London you could calculate how many passengers per day land on London´s airports. Assume there is only one runaway which only half of the time is used for landings. Do it yourself and calculate a number of passengers landing on London per day.
Then, to improve a little bit your numbers you can say that 1 out of 1,000 of the remaining population of the UK will have to travel to London. When you get all your numbers you can say that the average number of days that people stay in a hotel is 5. With all that data you can give a reasonable answer that it is not too complicated.
Do not forget to show them how "smart" you are. Mention AirBnbs, trains, ships, etc.., but get a reasonable number as fast as possible!
Best,
