The wife & I REALLY needed to get away, so we went to Paris for 8 days in May. We left our 1.5 year old in our house with my sister for 4 days, then they went to my parents for the rest of the time. The baby had a great time with aunt, bubby and zeidy, and we had a great time away. Baby was kept so busy he hardly knew we were away.
Word to the wise – we bought (for about 15 euros) 10 hours of Internet time at our hotel, and brought along a smartphone w/ Skype. We spoke to my sister and our baby every night via Skype.
