Connection Advice at LHR

My 78 year old mother and I are arriving in the AM on VS 006 from MIA and traveling at 16:30 to Barcelona on Iberia. We intend to check our luggage to LHR, collect it, proceed through immigration/customs and then head to the Revivals Lounge.

When they close the Revivals Lounge at 13:30, what would be the best way to get ourselves and our four or five bags to the proper departing Terminal for the Iberia flight to BCN?

Advice, as always, is appreciated.

Thank you

Ok Iberia departs from Terminal 2 and the only real way to get there from Terminal 3 is the 5-10 minute walk through the subway. You can take a trolley with you the whole way for your luggage so you won't have to carry it
