All of my 50 guests are OOT.  I   chose the church, reception, hotels, rehearsal dinner all within 5 min's of each other via taxi, all by the Riverwalk so people wont have to rent cars and pay parking.  We are providing  transportation from the church to the reception (5 minutes) because it  would be hard to get taxis at the church. 
 Now, my family is the problem. They are asking me to find a house for   them to rent so they can all be together and save money since they're flying from NY. This would mean   not staying dowtown (none available there) and they need to   rent a car and pay downtown parking so now all their expenses go up. 
  One sister has a 3 and 6 year old and complained she cant take taxis   around dowtown because she would need to carry a car seat. (really? for a   5 minute ride?).   There are 3 sisters, 2 married, plus my parents, all   flying in diferent days and times so I cant think of a way to help  with  their request for airport transportation. I suggested they rent 2 suites with king beds at$119/night at Drury if they want to save and just have the kids sleep with my single sister. I did   find them one house dowtown ($500 for the entire weekend) but they waited didnt want it then changed   their mind but too long and my other guests rented it.
 Part of me  feels like saying do whatever you want, if you dont like my   suggestions, which were meant to be convenient and cost effective.  Then again, it's my family so am I being unreasonable? Any advice on how to handle?
