Which member or members of the speaker’s family have health problems? Why didn’t the family go to Rotorua?

Interviewer: What was your holiday location and how did you hear about it?
Interviewee: My holiday location was Waiwera, in New Zealand. It is a thermal spa resort. I was there last year with my parents, my sister and a couple of friends of my parents. My father and my little sister, who inherited the medical problems from my father, need to go to a thermal spa every year for treatment. They used to go to the Polynesian Spa in Rotorua, another famous resort in New Zealand, but last year they decided that they fancied a change. I had never gone with them to a spa because I preferred to spend my holiday at home or go to other places, but last year when they changed the location I decided to go with them. I also decided to go because my sister really wanted me to go with her. My parents found out about this location from some of the people they met in Rotorua. These people said that they were more satisfied with the accommodation and facilities at the Waiwera spa, so my parents were curious and when they returned home they asked me to search on the Internet for some information. They were impressed with the information I found and it was then that they decided to plan a trip there.
Interviewer: So you went with your family and your parents’ friends.
Interviewee: Yes. I travelled with my parents, my little sister and some family friends with their three children, so that altogether we were nine people. I was lucky because in the other family there was a boy one year older than me so I had someone to pass the time with and have some fun. There were a lot of elderly people and kids at the spa town, so I was happy that he was with me. We had similar interests. It’s good to be with someone with your own age when you are on holiday.
Interviewer: How much time did you spend finding out information about this spa?
Interviewee: I didn’t spend so much time searching for the information be- cause the spa has website that was easy: to find. We wanted some more information that wasn’t on the website, particularly about how to get there, but we went to a travel agency and they gave us the information that we didn’t have and made there the reservations for all of us.
Interviewer: Can you tell us the thing you like most at the spa?
Interviewee: There were so many things that I liked there. I especially liked the accommodation. We stayed at the Waiwera Holiday Inn which is situated right on the beach. It offers spectacular sea views. I think that I will never forget it.
Interviewer: Were there any things that you were not satisfied with?
Interviewee: I think that the bad side of this vacation was that there were so many old people and many many children. Luckily, there were some play areas for children and they stayed there most of the time.
Interviewer: How was your room? Did you have everything you needed?
Interviewee: Yes we had everything we needed. Everything was comfortable and the conditions were great so I have nothing to complain about.
Interviewer: Did you make any new friends? Are you still in touch?
Interviewee: Everyone was very gentle and warm. They really made a good impression. When we needed some help they were very helpful and I felt great. I’m still in touch with the son of my parents’ friends.
Interviewer: How did you spend your time? Did you participate in any recreational activities?
Interviewee: I don’t have any medical problems like my father and sister, but I still went to the thermal spa. There were a lot of recreational activities to enjoy if we wanted. For example, I played golf because there was a mini golf course. Basketball and volleyball were also available, but we couldn’t get enough people together for two proper teams. I also went to swim and I also went scuba diving on the reef not far from the hotel. There was a small group of us with an instructor. It was truly amazing. I cannot describe in words how I felt down there. It was like I was in paradise.
