<human>: My parents are going to Russia in 6 weeks to celebrate their 40th wedding anniversary, and are both very excited about it as it is one of the few countries they haven't been to together.

The only thing that's detracting from their excitement is the fact my mom had to have foot surgery done in late January, and is still recovering. She can walk around in an aircast now, but she still gets tired pretty easily because she hasn't been able to build up her stamina. Both of my parents are in pretty good shape for their age, so they would like to still be able to see and do as much as they can while they are in Russia (they will be in the St. Petersburg area).

My mom's doctor thinks she will be in pretty good shape by then and will be able to walk in shoes with orthopedics in them, but again she may not have the same stamina as she used to.

So, on that note, I was wondering if anyone could provide some tips for how to see Russia with less walking (but not touristy bus tours), or similarly if anyone can think of a really good Mother's Day present that would somehow be helpful while she's out there.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: My mom had surgery on her foot and is going to Russia in 6 weeks. What's a thoughtful present that will make her trip more comfortable? Thanks!
