AlohaActually as a newbie, I agree with you , after being here only a week, if you read only this site, unless you can travel with a sleeper, you are going to have a miserable time... I would suggest a coach only section. We have decided to drive as it became pretty apparent from reading here that traveling with kids is discouraged unless you have a sleeper.Hey, all I can do is point out how this looks from outside AU's echo chamber. Choosing to believe it or not is entirely up to you.Relax. We are here to be helpful not lobby for everyone to take sleepers.
While a sleeper is more comfortable, Coach is OK, depending on a number of circumstances. The more flexible the body the better. Another thing none of us ere can tell how well your toddler will react. If your is a quiet one things will go well, If yours is a "squirmier" maybe not.
Since I turned 50 I have done several overnights in coach,with no problems, guess I have been lucky to have well behaved youngsters in these coaches, and I enjoyed seeing them observe everything around them.
