Headed east we usually want to spend at least three days in the embarkation city (if I have flown that far I enjoy exploring that city). We usually land in the morning, drop our bags at the hotel and if possible take a shower. Then we head outside to walk our feet off, get fresh air and sunshine. Keep going until about 8 pm local time. Now heading back west it takes us longer to acclimate and quit waking up at 3 am. This year we are doing the eastbound TA instead of flying - I know we lose and hour most days but that will not be an issue for us.
