请问有谁在alamo uk租车的经验啊，有事想请教

本人6月底，7月初计划美国游，准备洛杉矶提车，玩好黄石后，就盐湖城还车，这样不可避免的会有异地还车的费用。最近研究了很多大家关于租车的帖子，一些大家推荐的网站：expedia uk,alamo uk,carhire3000,economycarrentals,发现通过alamo uk订车价格还算可以，14天，车型Minivan Dodge Grand Caravan or similar，加上异地还车的费用如下：

Collision Damage Waiver Full Included

Extended Protection Included

Fuel Service Option Included

Airport Concession Fee 11.11% Included

Customer Facility Charge Included

Tourism Fee 2.85% Included

Mtr Veh Fuel Sales Tax Included

Sales Tax Included

Unlimited Mileage Included

3 Additional drivers Included

1 Tank Of Fuel *Except When Picking Up at Manhattan Locations* Included

total: £480.20

Additional charges are mandatory and you will need to pay these when you collect the vehicle.

All additional charges are subject to local taxes and for your convenience we have displayed them below at the current rate applicable.

One Way Charge $297.80

Airport Concession Fee 11.11% $33.09

Sales Tax $30.61

Total additional charges: $361.50 (approx. £228.20)

我算了一下汇率，将alamo的2笔费用相加后的价钱和economycarrentals.com的价钱差不多，但alamo毕竟提供了一箱油，感觉alamo好像更核算一下。

请各位大侠帮忙看一下，这个alamo提供的保险是不是都涵盖了？CDW肯定有了，SLI不知道是否提供？另外就是后面的附加费用是在拿车时候付的，是不是差不多就是这个价格？不会有很大的调整了吧，害怕隐性消费啊。。。

多谢了
