Mr and Mrs Robinson's friends had often told them about their wonderful holidays in sunny Spain, so at last the Robinsons decided to try it for themselves. They collected a huge pile of brochures from travel agents and chose a two-week holiday on the Costa del Sol at a magnificent-sounding hotel five minutes from the beach. It was to be their first holiday abroad.
Things began badly when the plane was delayed at Heathrow because of technical problems. The Robinsons finally fell into their hotel bed exhausted at about two o'clock in the morning.
Next day they drew back the curtains and found that their room had a depressing view of a warehouse full of huge crates. “ Isn`t what we were promised”, said Mrs Robinson. “In the brochure it says all rooms overlook the sea.”
Mr Robinson went at once to make a complaint. but the manger pointed out that by standing in a corner of the balcony and craning your neck to the left, you could in fact see a little bit of the sea. The Robinsons had to admit that
it was just visible, although they couldn't help feeling rather
cheated.
After breakfast they set out for a closer look at the sea. The “five minutes”, from the hotel to the beach turned out to be over half an hour. Mr Robinson was by now losing his temper. He hurried back to the hotel and demanded to see the manager again.
"The beach isn't five minutes walk away”, he shouted. "We walked for at least half an hour." “Ah”,said the manager, "but it's only five minutes by car." This reply left Mr.Robinson speechless.
Things went on like this for several days. The Rbbmsons couldn't stand the food; the disco kept them awake at night; the walk to the_beach seemed to get longer and longer. After four sleepless nights they flew back to England, and they spent the second week of their holiday sitting out in the garden. It wasn't. as hot as the Costa del Sol, but they found it a lot more relaxing.
