My husband and I will be going the UK for the first time for seven days, and it will be our first trip abroad. We would like some help with what all things are essential to take along with us, which we may not find there. The main reason for our travel is to see what the UK looks like and visit some of the famous tourist places. We don't know anyone in the UK so our stay will be in a small hotel. Please provide a checklist for UK travel from India.
