Would anyone be so kind as to proofread the following text? I was not quite sure whether the phrase "overnight trip" was correct but what I meant was a field trip during which the students and teachers slept outdoors in the tents

The new school year started with an overnight trip. New teachers and students had a golden opportunity to get to know each other better. The weather didn�t spoil our plans and turned up to be  much better than we had previously expected. As a result,  we did not freeze so much. After we had covered a short distance  from the road to the camp school, we wolfed the lunch down. After the lunch everyone took to water sports and had a go at canoeing, steering a boat or kayaking. All students got a unique opportunity to practise their skills to their heart�s content. But the major challenge that faced us was to get hot water in the hot tub. As it turned out, pumping the water into the tub and having it heated in an oven was no a walk in the park. The students were very anxious to have the water pumped into the hot tub and in the end they managed to do so.  Finally, the hot tub was bubbling and splattering hot water and some courageous students had taken a dip in the lake before they plunged in the tub. Such was the joy that almost the whole school wound up in the tub in the end. In the evening, some parents paid us a visit as we were barbecueing and  enjoying ourselves around the bonfire. The night in the Sami tent was an experience in itself. Early in the morning we had breakfast, paddled a little more in the canoe, packed up and went home. What a great overnight trip we had !
