Although not absolutely necessary, I would prefer to check our bags on our trip from TPA to MIA so as not to have them in the way. We have a bedroom, but nowhere we HAVE to be immediately once we get to Miami. Is there any reason why I should NOT check our bags? Does it take a long time to get them when we arrive? Is it OK to lock them with the TSA locks? Do we even need to lock them? This is our first train trip. I appreciate your replies. (By the way, this site is WONDERFUL. Thank you to all the nice "regulars" who take their time to answer all these newbie questions. Your advice is priceless and so appreciated).
