For that opening sentence, I'd go with something along the lines of this: "If I had to summarize my summer vacation, I'd say it was uneventful, but enjoyable." "My summer vacation was busy to say the least." "I didn't have the best time with my summer vacation, but it certainly was a vacation." "I spent my summer vacation the way kids are supposed to; doing absolutely nothing." "This year's summer vacation was the best I've ever had, and I'd love to tell."
Summer vacation was a blast! I waited a long time for this summer vacation, and it was worth it. My summer has come to an end now, but I will forever treasure the memories I made.
