We went Mar 22nd when we arrived I had heard we could keep luggage and not do 2nd collection. I did not intend to do this and continue as in the past as I have never had a problem with 2nd collection, always arrived around the same time as me but whne we got there last month I saw they has intalled a new escalator at side of bag drop so decided to try it, it worked great, escalator takes you right upto the train. Unless I had loads of luggage I would not use 2nd collection.
For arriving back at MCO after your holiday they have now moved to other side, A, had no problems there but security lines were ridiculous on 5th April. at least 50-70 people in every line, it was chaos, took about 30 mins to get thru.
