denis to speed you collecting process along you may want to search the web for coin shops in the cities that you will be visiting. I have no personal knowledge of any shop in the cities that you will be visiting but I would recommend the following strategy for you.
1: Select what you want to collect either a circulating collection which would consist of coins from Denver and Philadelphia. Trying to get the uncirculated and silver proof sets from the San Francisco mint might prove to be very daunting unless you happen to get lucky.
2: Select the type of album that you are going to use.
3: If you are going to try for just a circulating set getting rolls of quarters from a bank will reduce the overall cost. The three cities that you listed would be great for getting coins from both mints.
However the big limiting factor will be the amount of time that you are planning on spending in the states.
Enjoy your stay.
