· I have visited Thailand four or five times and do not forsee any problems for you and your friend. Yes, if you were wheelchair-bound, you would have problems with the sky-train, high kerbs, uneven paving, etc, but as you are an able-bodied person, you will be able to get about easily. My advice would be to drink lots of bottled water, haggle when buying anything in a market, try all the wonderful foods and treat yourself to relaxing massages! Have a great trip.
