VVHT,
Since this is slow season, it is possible the numbers maybe somewhat down, but fairly close to normal. There are some really slow weeks during the summer.
All legal attractions are being made to comply with social distancing and hand sanitizing station regulations. Masks are available aplenty, everywhere you go you can get them. Same with hand sanitizer, you can buy it by the gallon. Haven't really seen many gloves around yet, but I am sure that will change soon.
There are zero new tourists now. Any is better than zero. I will ask your two final questions this evening, the first one seems a bit existential and I am pretty sure no one will know how many seats are booked. I am not sure the airlines do...
Thanks man!
