Can i have a celebration over a number of days and nights?

Again there is nothing to stop this but the longer noise is made, the greater is the chance that you could cause a statutory nuisance and that your neighbours will have a genuine complaint.
If you must have a number of parties over two or more days, you should make extra sure that your neighbours are prepared for this and agree with them acceptable finish times. These times might be earlier than you would like, but where people live close together and are easily affected by activities at someone else’s home, you do need to show consideration and courtesy.
