I'm planning a trip with older family members, and our top choice was India. Though, none of us has been anywhere in Asia, so we have lots of options of interesting destinations. This weekend we went on a walk with the family members, and one was having a good day physically and struggled with walking 1.5 miles. Are we headed into a bad situation trying to visit India with such physical limitations? Our other top option is Thailand, which is sounding better to me as we could mix relaxing time in beach resort and Chang Mai/Rai with more intensive time in Bangkok and possibly Siem Reap. Or am I overthinking this and Thailand will be similarly intensive to India?
