We were staying at the hotel for my 30th birthday ...

We were staying at the hotel for my 30th birthday and had approx 7 rooms booked in total between us.
2 rooms of the group were moved on the first morning of their stay due to construction work which was not mentioned prior to arrival or even upon arrival so a complete shock to the people in the rooms who had to re pack their things and then wait for a room to be allocated later that day. This made these people late to our breakfast booking so impacted upon the whole group. 1 of the guests has a member of your staff walk in on them in the morning without knocking. This was a lone female in the room as well so really not happy that they just walked in on the room! The construction work also started at 7am in the morning which woke most people up - again I appreciate that this can happen at this time but if we had been made aware earlier we could have potentially stayed somewhere else.
My room itself was lovely and had no issues but having other people have a bad experience did put a slight dampner on my birthday weekend!
