I was considering decorating my niece and nephews room when we stay at the GF in May. Is this acceptable? I was thinking about putting up streamers and balloons and maybe some other wall decorations. Do you think the hotel would mind if we used tacks and tape to put up the decorations? If I'm going overboard please tell me. I'm usually not quite this excited about a trip, but I have always wanted to take these two kids (ages - boy 4 and girl 2) to Disney World and I really want to make it special for them. My sister will be 5 months pregnant when we go, so I don't want to inconvenience her too much.
