im so sorry buddy. But the first one is incorrect. I said "keeping the enchantment intact". In order to reach via brooms, one has to undo the enchantments. It was depicted twice in the book. One as u mentioned and second when dumbledore and harry flew back seeing the dark mark. Dumbledore was murmuring the counter enchantments.
Oh.. So lemme try again0„20„2 On broomsticks ( Charlie's friends came this way to take norbart)0„20„20„2 By fireplace using choo powder ( weasleys, Harry & hermione went to 0„2Sirius'place like that when Mr. Weasley was injured )0„2
the second one(floo powder) is Right!
actually now i remember another one! So two are still left! 😛
