We would say that the vast majority of limo services that are operating in the current market are about as ethical as they can be, but suffice it to say that there will still be a few red flags that you should try your level best to be on the lookout for. Limo rental can be a real pain to deal with if you are not cognizant of some very specific things, and hidden fees are going to be at the very top of the list at the end of the day. Knowing about any secret charges that you would be forced to pay can go a long way towards helping you to stay within your budget for the most part.
Perhaps the most common thing that you would need to pay for without realizing it beforehand would be fuel. Now, this is not something that an ethical service provider like limophiladelphia.com would ask you to pay for, but there are some companies that will charge you a hefty hourly rate and also force you to pay for gas on top of all of that. You should always steer clear of companies that engage in such nefarious practices because of the fact that they will never have the customer experience at heart.
To put it plainly, hidden fees really only come into play if you hire the wrong service provider due to the reason that a company that is looking to optimize customer experiences will always be open and honest about any and all charges that you would need to pay. Just make sure that you tell them to give you a full list of charges beforehand and everything should go swimmingly for you all in all.
