Bus service San Juan to Caguas

Yes, it runs from the Tren Urbano's Coupey stop.

( From there several buses run from different direction; #9 to Old San Juan, #7 to Carolina, # 31 to LUMA  ekectric company and beyond... and to Caguas, a long distance luxurious looking BIG bus.)

Yes, runs from Tren Urbano's Coupey stop.

A big, luxurious looking bus. There are several busses run to different direction from there, #9 , #7, #31.....

@GHUCY Thanks so much! By any chance do you know the name of the company? (If not, that's OK, of course.) I couldn't find anything current online under "Alsa."

I'd love to be able to research this as much online as possible. I gather that for some of the inter-city transport it's more like you have to figure it out in person, but when you said "big luxurious bus" I thought it might be a company with an internet presence.

Thanks again.

I did not look who operates it  because I was not interested. But it is cheap and goes very often. ( I only know that for retirees it cost only $1, and maybe $2 for others?) I saw it many times while waiting for different busses at Coupey.
