I've looked at this a few times myself and that's really the only option: take either the Capitol Limited or Cardinal to Washington, then catch the #66 to Boston. It'll get you there early enough to connect through to Camden. It is bookable, but as a multi-city trip (ALN-WAS, then WAS-CDN). I don't know if AGR would be able to book that or not. The alternative is taking the Lake Shore Limited to either Boston or New York and spending the night. If AGR can't do it I'd just use one reservation to get to Boston and book the Downeaster separately. It's not all that expensive.OK I was just futzing around at amtrak.com. I tried BON - CDN (Camden) and it looks like there is only option. The downeaster to a thruway bus connection. The bus is 8254 and it leaves Portland, ME at 2 pm. It looks like you will have to be able to connect to a downeaster that arrives in Portland, ME prior to that in order to make the connection, which is why your choices are probably so limited (or nonexistant). I don't think this trip will be possible without some sort of overnight, or unless you take Cap to the 66 and arrive early morning into BOS.
EDIT: putting in PVD - CDN does provide the 66 into BOS, self transfer to BON, and then the 681 downeaster to the thruway bus connection.
You could book this multi-city, but if you are trying to do an AGR award trip, I am not sure if you will be able to book it if arrow doesn't spit it out as a possibility from your origination station.
