Can we park with jeep and travel-trailer in their parking (35ft combination)

I would not try this!

You might wanna avoid bringing the trailer onto the strip in general. I would not attempt to bring it into the parking garage. One mis-step and your stuck. Another consideration is Max height. My truck is 6'5", and was concerning in some of those garages. That have oversized vehicle areas, but they were full when I was there last.

I agree its underground parking, I would call.

I don't think so. It's all underground parking. Call the concierge for more info.

I cant imagine why not. The only thing I would say is that you might want to park somewhere where there ain't a lot of cars so that you cansuccesfully park the trailer and your jeep
