The lost suitcase

It was a lovely sunny day. My family and I were planning our summer holiday, my father was washing the car while my mum was packing the luggage. Everything was ready, in ten minutes we were going to set off to the beach.
Suddenly, my mother realised that we had lost my suitcase. She looked for it in each room without success. We couldn´t spend more time looking for the suitcase because we had to arrive at the airport in time. So, we decided set off without it.
Finally, when we arrive(d) at the hotel, we went shopping and I bought some clothes.

My family and I were getting ready for planning  (planning is something you'de do weeks before you left) our summer holiday vacation (maybe holiday sounds good in England in the US it would aound odd) , my father was washing the car while my mum was packing the luggage. Everything was ready, in ten minutes we were going to set off to  for the beach.
Suddenly, my mother realised that we had lost my suitcase. She looked for it in each room without success. We couldn´t spend any more time looking for the suitcase because we had to arrive at the airport in on time. So, we decided  to leave  set off without it.
Finally, when we arrived at the hotel, we went shopping and I bought some clothes.
