As salaamu ‘alaikum wa rahmatullaahi wa barakaatuh. Here are some gorgeous pictures of hotels in Jeddah. I did not view all pics (there’s soooo many), so view at your own discretion In Shaa Allaah. Some photos will have their own slideshow links right below them: Beautiful Hotel Photos – Jeddah
Yahoo Travel has reviews, and Q/A if you’d like to ask questions about Jeddah before coming. Regular local residents seem to be the ones replying.
