Bedika for Hotel Goers

do i need bedikas chametz if i’m going to a hotel for the whole Holiday?Bracha?

You need to do bedikas chametz the night before you leave. If it’s bedikas chametz night (this year Thursday night March 29) you make a bracha, before that you check without a bracha.
Either way you say Kol Chamira… (nullify all chametz) post bedikas chametz and again erev pesach.

Do I do a Bedikat Chametz in the hotel as well as home before I leave?

No need to do bedikat chametz in the hotel. But make sure to get rid of all chametz erev pesach!

Thank you
