I don't know about the presents but it would be wise to check with your travel insurance to confirm that you are covered for each leg of your trip.
Why do I say this ?
I know that if I travel to UK on a flight I have booked. Then travel onwards to say RP on a separate booking, most insurances will not cover me in the event that I miss the connecting flight in UK.
I know this to be true I have spoke to the assessors of several companies.
As a result of raising the problem with one broker, here in Spain, but a UK company, they know have now re-written a policy to ensure that such onward travel is included, but with the proviso that there is at least 3 hours between the flight arriving in UK and the one departing.
