I went to France in Sept for 3 weeks, after coming down with a breakthrough case exactly three weeks prior to departure. I have some thoughts for you--
I had plans A, B and C worked out in case I or my partner contracted covid over there. I had the blessing of my physician. I had extra meds, good insurance (including coverage purchased that covered Covid and a support person). I had the ability to have my home and pet covered here, and as I currently am not working, did not have to worry about a job to come home to.
Having said that, the 'mild' case of covid I had (after double vax with Moderna, and my second dose was end of March so well within the 6 month period still) was NOT that mild for a bit. It was very different than the 'flu' or a cold. Instead of one peak day and then recovery, it plateaued on about the third day and stayed there. Then it got better, then it got worse again. It took a full 11 days before I felt ready to leave the house, regardless of the CDC rec to self isolate for 10. I did attempt a half mile and a mile walk twice, on very nice days in the three week period before I left for France, and felt like I had run a marathon. (For reference, I AM a runner, I've been running steadily for 34 years and I also backpack 600-800 miles a year and sleep outside on those trips about 72 nights a year on average, plus I've been lifting weights for over 10 years. As a 51 year old female, I'm in pretty dang good shape.) I lost my sense of smell and taste on day 5 and it was barely returning when I left for France.
What that means, is, I spent two full days in bed (literally all day and into night) feeling awful. I could have done it in a hotel, but people really need to think about whether they can or not. I was sick. I felt sick. I watched TV most of the day on the couch, utterly exhausted. I drank an extraordinary amount of liquid. I alternated tylenol and ibuprofen round the clock. I had to take Flonase for my sinuses. I had a terrible cough for about a week.
Things to think about: will your hotel or airbnb have some form of media that you can watch? Will your data plan allow you to stream on your phone or laptop if not? What will you (or your support person) do to occupy yourself if this is not the case? I don't even think I would have had the energy to read honestly ( I didn't read at all, and I usually read every day). Can your support person and/or kids stay in a hotel for that long? If they are with you, they will need to continually test positive to go out, otherwise they risk everyone in France they come into contact with. My partner would have been ok staying with me inside. Can the facility you're staying at handle this, as in: is your location good for deliveries, etc? These are things that sound like they won't be an issue but they might be.
I think I could have handled it over there ok. But: it was worse than I expected it to be, and I did indeed feel completely wiped out in a way that I've never felt before except for a major health crisis. Everyone reacts differently of course-- but therein lies the rub. I just always try to imagine the worst case scenario, and now I have a better basis for this at least.
I'm sooooo glad we went, honestly. But for me, it was almost easier as I knew I would not get it again quite that soon. I am still planning on going to Greece in May of 2022, but that is barring anything getting worse of course.
Just a few things for you to really consider before you go. Bonne chance!
