None that I am aware of

It’s not bad on bikes, about 8 miles total. My wife and I actually hiked from the river walk to the first 3. It was actually enjoyable and with very little traffic it’s safe. One suggestion might be to drive to the first one and then rent the bike that are right on site. This would cut down the miles.

I strongly suggest doing a tour, but to answer your question, you pay at each Mission, or make a donation.

I am sure you can, but was not a lot to enjoy between sites also busy areas that may make a group bike a challenge The bus was easy , and if you use a car plenty of parking

You may have already gone, but we did it by car.

I have to imagine that stretched on time also means stretched on driving all over to see them. there may be many around SA, but there are only 2 more in the park; Conception and Capestrano. go with Conception

Hey Michael, not sure on that service but we received excellent guidance from the visitor center across from the Alamo. I am sure they can answer your question. We rode the rental bikes one way and were able to drop the bikes off at the last mission and take an Uber back to downtown for $23 . That made the ride easier for this 50 year old dude! The visitor center number is 1-800-447-3372. Happy travels!

I'm sorry, but the answer to that question depends so much on personal preferences it is very hard to answer. There are dozens of good hotels in the Riverwalk area if you want to stay there. If you are looking for less expensive, then stay away from that area and look out at the airport or other outlying areas, but you'll lose the accessibility and charm. Some of the neighborhoods to the south and in the mission areas are not the kinds of areas you'll find hotels in. So, I'd focus on the Riverwalk or Pearl River/Brackenridge Park area if you are a first time visitor and want some nice walking distance destinations from your hotel. If you are into historic B&Bs, then maybe the King William district south of the Riverwalk. Your choices/costs will be heavily impacted if there is a major convention in town (as there often are).
