We have a flight departing Heathrow at 10:05am on a Friday morning, from Terminal 3. We are looking for a reasonably-priced hotel for the night before, with a convenient and easy way to get to Terminal 3 in the morning.
Since we are a family of 5 (2 adults and 3 teenagers), all the hotels are requiring 2 rooms. It appears that the Hilton at Terminal 2/3 would be the most convenient, but the cost is about $920 for the one night (ouch!). So we are looking at other options.
The Premier Inn at Terminal 4 is about $200 for the night (much better!), and the Atrium Hotel at Hatton Cross is similar.
My concern is getting to Terminal 3 from either of these locations on the morning of our flight. Everything I've read says "if you're leaving from Terminal 2/3 stay near the Terminal 2/3 hotels". But it looks like we should be able to take the Underground from either of these hotels to Terminal 3, pretty conveniently, for free, and with enough time for our 10:05am flight. Am I missing something?
If this approach makes sense, then any opinions on Premier Inn at Terminal 4 versus the Atrium Hotel at Hatton Cross, in terms of quality or convenience? (since both are similarly priced)
FYI - we would prefer to avoid taking a bus to Terminal 3 in the morning, since we've had problems on other trips where we couldn't get on a full bus, and nearly missed a connection. So taking the Underground to Terminal 3 feels more reliable and lower-stress to us.
