In next extract from a text while reserving a hotel room there are some final 的.
1: 请问你们旅馆有没有免费接送服务?
2: 有的。请问你们星期三几天到?
1: 早上六点40分到达海南国际机场。
2: 好的,到时候会有人接机的。先星期三见。
In the last ..example 到时候会有人接机的 II have seen in the next grammar point that is a modal particle used preferably with 会。

But what about the simple 有的 and 好的. ¿what grammar refers to this two cases?. I cannot find any.
