I'm planning to spend the last full day of my trip in Bath. I have a room scheduled at a Heathrow hotel for that night. So my plan was to go back to our hotel in central London, grab our bags, and taxi to Heathrow (yes, I know there is a train, but we'd need a taxi to Paddington anyway and it isn't that much more expensive to just take a taxi all the way, and it is easier for me with bags). The reason for the airport hotel was a combo of ease the next morning and saving a little money.
Now I am wondering if I could/should bring my bags with me to Bath and spend the night. I can find a cute hotel for even cheaper than the airport hotel (although that is in no way the deciding factor). It looks like I could take a 6:43 AM train (ouch), transfer at Paddington and get to Heathrow by 8:40. I like to be three hours early as recommended for intl flights and want a cushion due to the distance of travel. I am just wondering -- is this too far away to really be safe to get to my flight? It is early January, in case that matters (not New Years Day itself). Am I better off with my original plan? I just thought it might be nice not to do so much traveling the night before we leave and not be worried about leaving Bath earlier than we might want to. I'm really evaluating in terms of fun/convenience/safety of making my flight, not in terms of $$$.
