The "Exact" match campaign generates the maximum conversions and also gets better CTR and position compared to "Broad" match campaign.
For my experience better organization for groups is to put in the same group all 3 matches:
(or the latest two)
A user write hotel in Google and click your ad.
Google will assign 1 impression and 1 click to [hotel]
Take also care of broad match because Google will use also "related" keywords like bed and breakfast which could be VERY different for what you expect.
