Answer:
This question is incomplete but I will give you an example of how a paragraph on an unusual summer vacation could be, then you can use it or adapt it as you wish.
Step-by-step explanation:
My vacations this year were different than in previous years. We planned to go to Grandma's field like every year, but on the way we ran into a big storm that prevented us from continuing. We had to seek refuge in a nearby farm and to my surprise it was full of animals! We liked the place so much that when the rain stopped, the owner invited us to stay and we did. It was a very fun and unusual vacation.
To write a good paragraph, you must first define a topic, or "something to talk about." You should think about the topic sentence and express it taking into account that it has the necessary elements to present a complete thought.
