person A: My brother and a bunch of our friends planned to go to a 15-person cottage in July.
person B: Oh my_comma_ that sounds like an absolute blast!
person A: It was. At that time_comma_ I couldn't wait for all the fun and games we would experience!
person B: Did you stay for long? That would be a great vacation. 
person A: We stayed for only 4 days because it cost us about $200 each for four days and nights_comma_ but I hope we can book it for a whole week or two next summer.
person B: What a great time! Is the cottage on a lake?
person A: It's very close to a lake_comma_ it probably takes a two minute hike down through a patch of trees and tall grass to get there.
person B: Sounds like heaven!
