When will both customers be free to travel?

Agent: Good morning. Can I help you?
Customer 1: Yes, good morning. We’d like to book a holiday for July, please.
Agent: Certainly. Where did you have in mind?
Customer 1: Oh, well, we haven’t thought a lot about it, really. We’d just like to go somewhere hot, you know, and it must be in July.
Agent: I see. Well, let’s get the dates cleared up first, then we can see about availability. What part of July were you thinking of?
Customer 2: Oh, well, you see, we have slightly different holidays. I’ve got the whole-month except for the last five days, so I could go from the first to the twenty-sixth, but my friend here doesn’t start until the seventh, so I suppose it will have to be the middle two weeks really.
Customer 1: Yes, but I’ve got to be back before the twenty-third.
Agent: Ok. Now, let’s find a destination. Any preferences, France, Italy?
Customer 1: Oh, not France. We went there last year and it was absolutely packed with teenagers making noise and getting drunk all the time.
Customer 2: Yes, it was terrible. We definitely want somewhere quieter this year.
Agent: Well, of course it depends more on the resort rather than the country. There are resorts in every country which can cater for the family or the slightly older person. They’re usually a shade more expensive, though, as you might expect.
Customer 1: Oh, well, we don’t mind paying a bit more if it means more peace and quiet, do we?
Customer 2: Definitely not. It’ll be well worth it.
Agent: All right. Let’s have a look at what we’ve got on the computer, July was it ten or fourteen nights you wanted?
Customer 1: Oh, the fortnight, please.
Agent: Right. Well, let’s start with Italy. Umm, we’ve fourteen nights bed and breakfast in Sorrento for three hundred and forty-five pounds, from Manchester, on the fourteenth, or we’ve got.
Customer 1: No, wait a minute, that’s no good for me. We wouldn’t get back till the twenty-eighth, and I’ve got to be back at work before that.
Agent: Oh, yes. Umm how about Sweden, two weeks, hail-board?
Customer 2: How much would that be?
Agent: That would be five hundred and forty pounds, from Manchester again.
Customer 1: Well, five hundred and forty er that seems too much.
Agent: Well, Sir, there’s surcharge for the airport, and it is a five-star hotel.
Customer 2: Oh, well, it’s a bit over our budget, really.
Agent: All right. Let’s try somewhere else: How about Portugal?
Customer 2: Oh, that sounds great. We’ve never been there before, have we?
Agent: Let’s see now. We’ve got fourteen nights in Albufeira, half-board, from Gatwick, for three hundred and eighty-five pounds.
Customer 1: Albufeira? Oh, wait a minute. Did you say the flight was from London?
Agent: That’s right, from Gatwick.
Customer 1: Oh, well, really, we’d prefer a flight from the north somewhere, Manchester perhaps, or even Glasgow.
