Ok everybody thinks it is great you retired but did not answer your question.
Obamacare is rough, the big issue is with insurance is " out of network" care which is care away from home, it is buried in the fine prine of the official rules of the plan, which is hard to find for a lot of plans,
the deductible goes very very high for out of network i have seen some plans as high as 200k per year.
Very few plans will let you travel and give good coverage, the emeregency room coverage is a scam as the deductible kicks in as soon as they move you to a hospital room, some employer plans do better in out of network then obamacare, obamacare will not let you easily send bills to anywhere but your house. Many doctors wont take obamacare in your home town , let alone out of state, so you will have to pay and try and get a refund.
