I am arriving at Heathrow airport with my husband and 2 children 11 and 12 years on 27 July at 11:15 pm. Giving ourselves 45 minutes for exiting the airport, it will be around 12 am. We don't have large bags, just carry on trolly bags of small sizes. I wonder about the cheapest and the safest method of getting to the hotel in Cromwell road (Cromwell crown). I know that on Piccadilly line the Gloucester road underground station is very close, the hotel is about 5 minutes walk from it.
my questions are:
1- When does the last underground on Piccadilly line departure from the airport, I mean it will be 12 am is there a metro at this time ?
2- Is it safe to walk with the children and the trolly bags from the Gloucester station about 5 minutes to get to the hotel which is on the Cromwell road itself.
3- Can I take the Piccadilly line (if there is a train at this hour) then take a taxi to avoid walking (if not safe). How could this be done I mean is it possible to take a taxi from the street just like that at this late hour ?
4- Is there an alternate cheap option to this ?
thanks a lot.
