I went to Bali 2 days after the first explosion.Felt really safe.Please do not cancel your reservation as Balenese are the nicest people on earth.They do need our help at this bad time again.If you want you can do as i did,i filled a suitcase with burn medicine,cotton ,etc... and donated it to the local hospital.You should see how gratful those people are.
Enjoy your trip Bali is really the paradise island.
