Answer
Start by comparing the option against the practical details that will affect the experience, not just the headline price or a few attractive photographs. For temple visits, confirm opening times, dress, shoes, photography, donations, transport, accessibility, ceremony times, language support and behaviour around monks or worshippers.
A temple is an active religious place, not only a tourist attraction. Quiet observation and following the site's own guidance are more important than getting a particular photograph.
Ask for the important points in writing before paying or making a firm plan, especially anything involving availability, safety, deposits, inclusions or cancellation. Current operating details can change with the season, weather and staffing.
A reliable provider or organiser should be willing to explain what is included, what is not included and who will take responsibility if plans change.
