You have a claim... the real issue is whether the expense of litigation will outweigh the extent of the injuries that you suffered.  The value of personal injury claim usually starts with the value of the initial injury.  If you were able to resolve the bug bites without any medical intervention... then this probably is not the most cost effective claim.  If you did require medical attention, you may want to hire an attorney to start with a demand letter to ask the hotel to reimburse you for your expenses.Because most bedbug cases don't warrant major litigation, many people simple go online and make online reviews reflecting the issues with the hotel to warn he next set of consumers.
